Bad config in `.gitconfig` causes wrong error in lazygit

**Describe the bug**
Bad config in `.gitconfig` would cause wrong error generation by lazygit

**To Reproduce**
Steps to reproduce the behavior:
1. mess up your `~/.gitconfig` (in my case I had a typo in `editor`) and save it
2. go to a git folder
3. run `lazygit` which throws this error:
> 2022/07/11 09:25:57 Git version must be at least 2.0 (i.e. from 2014 onwards). Please upgrade your git version. Alternatively raise an issue at https://github.com/jesseduffield/lazygit/issues for lazygit to be more backwards compatible.
4. in the same folder try `git status` and see this error:
> fatal: bad config line 15 in file /home/mehrad/.gitconfig

**Expected behavior**
I expected that lazygit produces an error that points to the correct issue. imho the git error is clear enough and that can be used.

**Screenshots**
Note that the error code of each command is printed at the end of the next prompt, so git's error code is 128 and lazygit is 1


**Desktop (please complete the following information):**
