Support for git worktrees

[awinki]

Description

I use git worktrees a lot on my machine, but i can't use our nuke build script to build our solutions. I always get the following error:

Unhandled exception. System.ArgumentException: No parent Git directory for 'D:\Development'
   at Nuke.Common.Assert.NotNull[T](T obj, String message, String argumentExpression) in /_/source/Nuke.Utilities/Assert.cs:line 73
   at Nuke.Common.Git.GitRepository.FromLocalDirectory(AbsolutePath directory) in /_/source/Nuke.Build/VCS/GitRepository.cs:line 49

Instead of a ".git" folder there's just ".git" file, when working with git worktrees.
