`latestdoi` badge link failing when latest record deleted

[ptamarit]

Package version (if known): 3.0.1

Describe the bug

The latestdoi badge link is failing when then record linked to latest published release has been deleted

Steps to Reproduce

1. Integrate with a GitHub repository and release 2 versions
2. Delete the latest record
3. Go to /badge/latestdoi/{github_repo_id}
4. The page fails with an internal error

Expected behavior

The page redirects to the latest non-deleted record (or at least to the tombstone of the latest deleted record?)

Screenshots (if applicable)

Additional context

Execution flow:

• This line retrieves the latest published release (but in our case, this latest published release is linked to the deleted record)
• Then this line tries to get the URL of the record linked to the release
• Since the record is deleted, self.record here is None, and accessing .data raises AttributeError: 'NoneType' object has no attribute 'data'.
• The part resolving the record is in invenio_rdm_records/services/github/release

To be fixed in invenio-github and in upcoming invenio-vcs.
