Nested git repo detection for symlinked repo

[lonix1]

A few months ago we got a new feature for detecting nested git repos: feature, PR.

But it doesn't handle the use case where the repo is in a symlinked directory. We have a number of common repos used in many monorepos, and they're referenced as symlinks:

MyMonoRepo/
  .git/
  lib/
    NormalNestedRepo/                  <--- detected
      .git/
    SymlinkedNestedRepo/               <--- not detected
      .git/
  src/

The symlinked repo is not detected.

(Unless this is already supported somehow @lszomoru @nteymory ?)

@lonix1, apologies for not getting back to you on this until now. There are several features (#5970) that are not working as expected when there is a symbolic link on the path of the git repository. I expect that this is something that we will look at when we try to tackle the symbolic link support.
