Reproduction steps

I have a file inside many folders (for ex : docs/jsons/myfile.json ) in my repository

I staged the file , so it now has the status "NewInIndex".

After that i made changes on that file.

It has now the status "NewInIndex, ModifiedInWorkdir".

My code is the following :

using ( var repo = new Repository("my repo path")
{
CheckoutOptions options = new CheckoutOptions { CheckoutModifiers = CheckoutModifiers.Force };

repo.CheckoutPaths(repo.Head.FriendlyName, new string[] {"docs/jsons/myfile.json"} , options );
}

I also tried to replace " repo.Head.FriendlyName" by "repo.Head.CannonicalName" and by "repo.Head.Tip.Id.Sha"

Expected behavior

I expect the file to get back to its previous content, and to have the status "NewInIndex" again.

Actual behavior

The file's content doesnt change and its status is still : "NewInIndex, ModifiedInWorkdir".

Version of LibGit2Sharp (release number or SHA1)

LibGit2Sharp version 0.26.2

Operating system(s) tested; .NET runtime tested

Window 10 Enterprise

.NET 6.0

从 CheckoutPaths API 开始，使用提供的路径和 CheckoutOptions，重现一个标记为 NewInIndex、ModifiedInWorkdir 的文件所报告的状态转换。验证强制 checkout 会恢复已暂存的内容，并使文件保持 NewInIndex 状态，以报告的 LibGit2Sharp 0.26.2 行为作为基准。
