LazyGit does not open inside a symlink'ed dir (which is under git)

**Describe the bug**
I have my scripts under git. My dotfiles install script places the scripts under ~/scripts
Trying to open LazyGit when in ~/scripts results in an error like below

```

**To Reproduce**
Steps to reproduce the behavior:

1. Have dir hierarchy under git VCS
2. Symlink (soft) a dir under the tree to another location
3. Navigate to location and try to open LazyGit
4. See error

**Expected behavior**
I expected to follow the symlink back, a dir which is under git.

**Version info:**
❯ lazygit --version
commit=v0.40.2, build date=2023-08-12T17:47:33Z, build source=binaryRelease, version=0.40.2, os=linux, arch=amd64, git version=2.42.1

❯ git --version
git version 2.42.1

**Additional context**
Running the logs I get
