Describe the bug
Commit hooks don't work on Windows with wsl2 installed.

run cargo test -p asyncgit sync::hooks::tests::test_commit_msg_no_block_but_alter

[2023-01-29T07:41:54Z TRACE asyncgit::sync::hooks] run hook '"C:/Users/hamflx/AppData/Local/Temp/.tmp4nwh43/.git/hooks/commit-msg"' in '"C:/Users/hamflx/AppData/Local/Temp/.tmp4nwh43/"'

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

It looks like gitui is using wsl's bash:

C:\> where bash
C:\Windows\System32\bash.exe

C:\> bash -c D:/tmp/echo_some_thing.sh
/bin/bash: line 1: D:/tmp/echo_some_thing.sh: No such file or directory

C:\> "C:\Program Files\Git\usr\bin\bash.exe" -c D:/tmp/echo_some_thing.sh
some thing

To Reproduce

run cargo test -p asyncgit sync::hooks::tests::test_commit_msg_no_block_but_alter on Windows(with WSL2 installed, and git bash not in PATH).

Expected behavior

unit test works.

Context (please complete the following information):

Additional context

[hamflx]

I'm trying to find git.exe, and using that to find bash.exe: hamflx@6480c01

For example, git.exe is located at C:\Program Files\Git\cmd\git.exe, then I remove cmd\git.exe from the path and add usr\bin\bash.exe, finally we get C:\Program Files\Git\usr\bin\bash. exe.

If this way is acceptable, I will make a pr.
