Description
When running new Repository(dir) on a sha256 enabled repo, it fails with a LibGit2SharpException stating unknown object format 'sha256'.
see: https://git-scm.com/docs/hash-function-transition
at LibGit2Sharp.Core.Ensure.HandleError(Int32 result) in /_/LibGit2Sharp/Core/Ensure.cs:line 154
at LibGit2Sharp.Repository..ctor(String path, RepositoryOptions options, RepositoryRequiredParameter requiredParameter) in /_/LibGit2Sharp/Repository.cs:line 35
At first glance it looks like libgit2 doesn't support this yet.
Version used: LibGit2Sharp 0.31.0, using LibGit2Sharp.NativeBinaries 2.0.323
To be fair: we only have one repo using sha256 for compatibility testing - and while git cli works great, 3rd-party tooling is still abysmal.
Contributor guide

Research direction
Start at the Repository constructor in Repository.cs:35 and inspect how Ensure.cs:154 surfaces the native error. Check the linked hash-function transition documentation and libgit2 support status first; done means opening a sha256-enabled repository no longer fails, with compatibility coverage established for this case.
