Unable to load shared Lib "git2-106a5f2" or one of its dependencies & "Negotiate" authentication is not supported

Reproduction steps

Our .net 6 app uses LibGit2Sharp 0.26.2 version . Our git is in Bitbucket which accepts Kerberos via SPNEGO. It all works fine in our windows environment. when we do dotnet publish ...... -r linux-x64 , I see that the 'git2-106a5f2' is also copied. A container is created with Linux/ubi7 to run the app, where we get the Unable to load shared Lib "git2-106a5f2" or one of its dependencies

Later I upgraded it to 0.27.0-preview-0182 which fixed Unable to load shared Lib "git2-106a5f2". However, it start throwing "Negotiate" authentication is not supported when Repo.Clone is called with CloneOptions.

CloneOptions is given a new DefaultCredentials() call back , to work with SPNEGO.

Version of LibGit2Sharp (release number or SHA1)

LibGit2Sharp 0.26.2 - Unable to load shared Lib "git2-106a5f2"

0.27.0-preview-0182 - "Negotiate" authentication is not supported

Operating system(s) tested; .NET runtime tested

.net 6

首先，在所述的 .NET 6 Linux 容器中使用 LibGit2Sharp 0.26.2 和 0.27.0-preview-0182，按照复现步骤进行操作。检查使用 DefaultCredentials 的 CloneOptions 回调，并比较这些版本之间原生库加载失败和 Negotiate 失败的情况。当相关失败可以复现，并且其受支持的解决方案或限制已记录在案时，即视为完成。
