config: rely on .gitconfig for verbose commit messages (#2664)

As discussed in https://github.com/jesseduffield/lazygit/pull/2599, it
makes more sense to have the user specify whether they want verbose
commits from their own git config, rather than lazygit config.

This means that we can remove all the code (including test coverage)
associated with the custom verbose flag, and lazygit will just inherit
the .gitconfig settings automatically.

Tested visually locally, as well as running the tests that all pass.
