workflows: Add explicit permissions for attestation

We have a number of jobs that nest the build-static-tarball
workflows later on. Due to these doing attest build provenance,
and pushing to ghcr.io, t hey need write permissions on
`packages`, `id-token` and `attestations`, so we need to set
these permissions on the top-level jobs (along with `contents: read`),
so they are not blocked.
