Error at launch with symlink .git file

### Describe the bug
I'm working in a project that recently underwent a large file migration. Part of that migration was changing the .git file to be a symlink to another location on disk.
After a fresh clone of the repository, when I try and open lazygit in the project folder, I get the following error:

```

```

In this case, my working directory is `/home/lee/Documents/projects/core/firmware/protected/redacted` (which is the location of the symlink .git file), and the target of the .git symlink is `/home/lee/Documents/projects/core/.repo/projects/firmware/protected/redacted.git`.

If I open lazygit in any subfolders, it doesn't recognize that it is within a git folder structure.

Calling git commands via the command line work normally (ie. `git status`).

### To Reproduce
Steps to reproduce the behavior:

1. Create a project that contains a .git file which is symlink'd to another location.
2. Open lazygit within the directory that contains the symlink'd .git file.

### Expected behavior
lazygit should behave normally and open the project like it would without a symlink.
