WSL and Lazygit

**Is your feature request related to a problem? Please describe.**
With WSL it is recommended to use `git.exe` instead to speed up certain operations. For example, in Lazygit, when trying to do a refresh, it takes a few minutes rather than just a second or two.

**Describe the solution you'd like**
Be able to specify the git executable e.g. `"/mnt/c/Program Files/Git/bin/git.exe"`

**Describe alternatives you've considered**
N/A

**Additional context**
Would love to use Lazygit but the above is preventing me from using it in a WSL environment.
