The set filemode is incorrect

Reproduction steps

Azure DevOps

1. Create YAML Pipeline just for monitoring filemode (show all files with filemode, script: git ls-files --stage) and create build validation policy for main branch

2. Create file "test1.sh" in folder "folder1", create PR to main and complete it

3. On new branch make changes, push it, hard reset to previous commit, create "folder2", move "test1.sh" to this folder, change filemode to 100755 (git update-index --chmod=+x file_name), force push, create PR to main and complete it

4. Switch to previous commit (before changing folder and file mode), push any changes, create PR to main and check build validation pipeline logs on the PR

Expected behavior

File mode is 100755 (new)

Actual behavior

File mode is 100644 (old)

Version of LibGit2Sharp (release number or SHA1)

14.0.29222.1

Operating system(s) tested; .NET runtime tested

Windows 10, .NET 4.8

使用 git ls-files --stage、移動到 folder2 以及 git update-index --chmod=+x 重現 Azure DevOps 情境。接著追蹤 LibGit2Sharp 如何處理所述 commit 與 push 序列中的檔案模式。對於受影響的檔案，當驗證管線回報檔案模式為 100755 而不是 100644 時，即表示完成。
