This bumps go-jose to the latest available version: v4.0.3.
This slightly breaks the backwards compatibility with the existing
registry deployments but brings more security with it.
We now require the users to specify the list of token signing algorithms in
the configuration. We do strive to maintain the b/w compat by providing
a list of supported algorithms, though, this isn't something we
recommend due to security issues, see:
* https://github.com/go-jose/go-jose/issues/64
* https://github.com/go-jose/go-jose/pull/69
As part of this change we now return to the original flow of the token
signature validation:
1. X2C (tls) headers
2. JWKS
3. KeyID

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.

Update the formatting of links and add a Markdown render hook for
handling relative internal links. Cross-references between markdown
files are now resolved the same way in both GitHub and Hugo.
