This commit fixes them. We are also bumping the linter version.

Enable configuration options that can selectively disable validation
that dependencies exist within the registry before the image index
is uploaded.
This enables sparse indexes, where a registry holds a manifest index that
could be signed (so the digest must not change) but does not hold every
referenced image in the index. The use case for this is when a registry
mirror does not need to mirror all platforms, but does need to maintain
the digests of all manifests either because they are signed or because
they are pulled by digest.
The registry administrator can also select specific image architectures
that must exist in the registry, enabling a registry operator to select
only the platforms they care about and ensure all image indexes uploaded
to the registry are valid for those platforms.

Harbor is using the distribution for it's (harbor-registry) registry component.
The harbor GC will call into the registry to delete the manifest, which in turn
then does a lookup for all tags that reference the deleted manifest.
To find the tag references, the registry will iterate every tag in the repository
and read it's link file to check if it matches the deleted manifest (i.e. to see
if uses the same sha256 digest). So, the more tags in repository, the worse the
performance will be (as there will be more s3 API calls occurring for the tag
directory lookups and tag file reads).
Therefore, we can use concurrent lookup and untag to optimize performance as described in https://github.com/goharbor/harbor/issues/12948.
P.S. This optimization was originally contributed by @Antiarchitect, now I would like to take it over.
Thanks @Antiarchitect's efforts with PR https://github.com/distribution/distribution/pull/3890.

Future-proof the version package's exported interface by only making the
data available through getter functions. This affords us the flexibility
to e.g. implement them in terms of "runtime/debug".ReadBuildInfo() in

The API for periodic health checks is repetitive, with a distinct
function for polling a checker to each kind of updater. It also gives
the user no control over the lifetime of the polling goroutines nor
which context is passed into the checker.
Replace the existing PeriodicXYZChecker functions with a single Poll
function which composes an Updater with a Checker. Its context parameter
is passed into the checker and also controls when the polling loop
terminates. To guard against health checks failing closed (ostensibly
healthy) when the polling loop is terminated, the updater is forcefully
updated to an error status, overriding any configured threshold.

Allow health checkers to abort if the request context is canceled.
Modify the checkers to respect context cancelation and return wrapped
errors so the caller of CheckStatus() would be able to discriminate true
failed checks from checks which were aborted because the context became
done.

The specifics of how the authorization for a request is propagated
through the registry app are private implementation details. Hide those
details from outsiders so they can be changed as needed without fear of
breaking third-party code. Move the utilities for attaching a request's
authorization status to its context and retrieving it from the context
into the registry/handlers package as unexported symbols.

The details of how request-scoped information is propagated through the
registry server app should be left as private implementation details so
they can be changed without fear of breaking compatibility with
third-party code which imports the distribution module. The
AccessController interface unnecessarily bakes into the public API
details of how authorization grants are propagated through request
contexts. In practice the only values the in-tree authorizers attach to
the request contexts are the UserInfo and Resources for the request.
Change the AccessController interface to return the UserInfo and
Resources directly to allow us to change how request contexts are used
within the app without altering the AccessController interface contract.

Our context package predates the establishment of current best practices
regarding context usage and it shows. It encourages bad practices such
as using contexts to propagate non-request-scoped values like the
application version and using string-typed keys for context values. Move
the package internal to remove it from the API surface of
distribution/v3@v3.0.0 so we are free to iterate on it without being
constrained by compatibility.
