fix(lazygit): support monorepo structure and other git providers (#3701)

## What is this PR for?
- The current implementation doesn't support multi-module/monorepo
project where `<repo>/.git` can be `gitdir` alias to the main `.git`
folder. This PR uses the Git CLI to resolve remote URLs to better
support flexible project structure.
- This PR also adds the support to Bitbucket and GitLab

What's the problem of reading `.git/config`?
- Not all information available there. For instance, some large projects
will split a monorepo into smaller submodules, where `.git` is a file
that contains the `gitdir` alias.
- There's no promise that `.git/config` has to be existed. Git supports
multiple ways to store the git info outside of the default git directory
like using `GIT_DIR` env variable.
- Have to do lot of reading and parsing logic.

Why `git remote -v`?
- Only contains remote info with explicit format. 
- Don't have to filter out other config info. 
- Don't have to deal with lots of weird edge cases.



## Does this PR fix an existing issue?
No.
