Features
- Incorporated a notion of container images' characteristics. Users can now filter manifests by their
nature using the `is_flatpak` or `is_bootable` field on the corresponding Manifest endpoint.
In addition to that, manifest's annotations and configuration labels were exposed on the same
endpoint too.
[1437](https://github.com/pulp/pulp_container/issues/1437)
- Updated the OCI manifest schema validation to comply with the changes from the OCI Image Manifest
Specification.

Bugfixes
- Fixed sync failure due to ignored certs during registry signature extentions API check.

Improved Documentation
- Migrated the whole documentation to staging. The documentation should be now consumed from the
unified docs site.

Deprecations and Removals
- Removed the optional "kid" parameter stored inside the signatures' payload generated during
docker manifest v2 schema 1 conversion. This change also removes the `ecdsa` dependency,
which is vulnerable to Minevra timing attacks.
[1485](https://github.com/pulp/pulp_container/issues/1485)
- Removed the manifest schema conversion machinery. If the manifest is stored locally in the newer
format and old clients request v2 schema1 manifest they will receive 404. v2 schema1 manifest is
still going to be mirrored from remote source during sync if available and passed to the old clients
on the request.
[1509](https://github.com/pulp/pulp_container/issues/1509)
- Deprecated `ADDITIONAL_OCI_ARTIFACT_TYPES` setting in favour of the relaxed validation.
