For now we only support .git/lazygit.yml; in the future we would also like to
support ./.lazygit.yml, but that one will need a trust prompt as it could be
versioned, which adds quite a bit of complexity, so we leave that for later.
We do, however, support config files in parent directories (all the way up to
the root directory). This makes it possible to add a config file that applies to
multiple repos at once. Useful if you want to set different options for all your
work repos vs. all your open-source repos, for instance.
