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.

go 1.21 added toolchain support. We should now specify a toolchain
version in go.mod.

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.

it is reasonable to ignore the error that the manifest tag path does not exist when querying
all tags of the specified repository when executing gc.

Currently, the `forcepathstyle` parameter for the s3 storage driver is
considered only if the `regionendpoint` parameter is set. Since setting
a region endpoint explicitly is discouraged with AWS s3, it is not clear
how to enforce path style URLs with AWS s3.
This also means, that the default value (true) only applies if a region
endpoint is configured.
This change makes sure we always forward the `forcepathstyle` parameter
to the aws-sdk if present in the config. This is a breaking change where
a `regionendpoint` is configured but no explicit `forcepathstyle` value
is set.

HEAD requests for instance return no body while still having all the relevant Content-Type headers set, causing unnecessary parsing errors. This skips further parsing for all requests that don't have any body to begin with.
