feat(dotfiles): add `git find` for finding files by name
feat(dotfiles): add `git find` for finding files by name

Basically saves me from the common task of doing:

    git ls-files | grep something

I already have a `G` suffix alias for `| grep`, which means I do:

    git ls-files G something

But this is going to be easier:

    git find something
