Push produce no errors but is not working if the local repo has .github folder

Summary

When using libgit2sharp to push an initial commit that includes a .github folder (with valid contents), the push fails silently — no error is thrown, and the remote is not updated. If the folder is renamed (e.g., to github), the push succeeds.

Steps to Reproduce

1. Create a new local repo
2. Add a .github/workflows/ci.yml file
3. Commit
4. Attempt to push to a GitHub remote (with or without authentication)

Observed Behavior

• repo.Network.Push(...) does not throw
• Remote is unchanged
• If .github is renamed, push succeeds as expected

Expected Behavior

Push should either:

• Succeed and update the remote, or
• Throw an exception if push fails

Notes

• Using latest LibGit2Sharp and .NET 6+
• Changing .github to any other folder name works

Environment

• LibGit2Sharp version: 0.31.0
• OS: Windows

使用包含 .github/workflows/ci.yml 的新仓库复现该问题，然后跟踪 repo.Network.Push(...) 针对 GitHub 远程仓库的行为。确认 push 是否会更新远程仓库，还是会报告异常，并验证重命名 .github 是否会改变结果。
