GitLab 16.9 introduced an option to create repositories with SHA256 instead of SHA1.

This commit exposes object format used by particular repository via Project API.

See https://gitlab.com/gitlab-org/gitlab/-/issues/419887

@jmini is it ok that repositoryObjectFormat is a string? Or it would be better if it was a enum, like project vsibility?

I am always not really sure about the String vs enum… In the docs they just mention sha1 being the default value but they do not say it is sha1 or sha256. So I think String is OK.

Yes, sha1 is default. The repository can either be created with sha1 or sha256. It cannot be changed after repository ws created. And it is very unlikely any new values will emerge in nearest 10 years or so.

So I think String is OK.

Ok.

Converting to draft until I fix test issues.
