"remote authentication required but no callback set" in pull after upgrading from 0.28 to 0.29

@bording we get the error "remote authentication required but no callback set" after upgrading from 0.28 to 0.29 when connecting to a company internal azure devops server.

This works great with the old version using windows authentication.

Reproduction steps

• connect to a company internal azure devops server via windows authentication

      Signature signature = GetSignature();
      PullOptions pullOptions = new()
      {
        MergeOptions = new() { FileConflictStrategy = CheckoutFileConflictStrategy.Theirs }
      };
      MergeResult mergeResult = Commands.Pull(Repository, signature, pullOptions);

Expected behavior

Success

Actual behavior

LibGit2Sharp.LibGit2SharpException
HResult=0x80131500
Message=remote authentication required but no callback set
Source=LibGit2Sharp
StackTrace:
at LibGit2Sharp.Core.Ensure.HandleError(Int32 result) in /_/LibGit2Sharp/Core/Ensure.cs:line 154

Version of LibGit2Sharp (release number or SHA1)

0.29

Operating system(s) tested; .NET runtime tested

Windows 11, .NET 4.8

Seems to be related to #2065 and #2087

Commencez par l’appel Pull et le chemin d’erreur dans Core/Ensure.cs à la ligne 154, puis comparez le comportement d’authentification entre les versions 0.28 et 0.29. Examinez les issues associées #2065 et #2087 et reproduisez le problème sur le serveur Azure DevOps interne sous Windows avec .NET 4.8. Le travail est terminé lorsque le pull affiché réussit avec l’authentification Windows sans la missing-callback exception.
