Fix git config get (--get is an option)

[lordkekz]

I tried converting a local git repo and it failed with the following error:

$ git prole convert
Error:   × `git` failed: exit status: 2
  │ Command failed: `cd /path/to/repo && git config get --null checkout.defaultRemote`
  │ Stderr:
  │   Fehler: Schlüssel enthält keine Sektion: get

To get a config entry, you need to write --get instead of get. With this PR, the error no longer shows up.

git config --get is deprecated, what version of Git are you on? I want to add a check so it errors out with too-old versions of Git.

Oh, you're right. I'm still on NixOS 24.05 and I guess they must've deprecated it since then. But I totally agree with the change, --get was weird.

Sorry for wasting your time 🙃

Edit: looked it up, git config get was added in git 2.46.0 according to the git docs. NixOS 24.05 still has git 2.44 btw.

Thanks; 2.46 is probably more recent than I should require. I should check the test suite on older versions...
