repo: add the field objects.format
The flag `--show-object-format` from git-rev-parse is used for retrieving the object storage format. This way, it is used for querying repository metadata, fitting in the purpose of git-repo-info. Add a new field `objects.format` to the git-repo-info subcommand containing that information.
