release: Introduce the release.sh helper

For now this script does nothing, but we're introducing it in order to
redduce the diffs for the next commits in this series.

My intention is to have as much as possible related to the release as
part of this helper script, and it'll be populated function by function
while replacing content that's "hard coded" (and duplicated) on
different GitHub actions.
