"Unsupported git service" when trying to create a PR with custom SSH alias

### Describe the bug
I use multiple SSH keys in my setup (work, personal, etc.). I configured custom SSH aliases for each account to ensure my commits and access to repos/organizations. This means i need to clone my repos using `git@github-work:XXX` and `git@github-personal:XXX` instead of `git@github.com:XXX`. I can push/pull, create branches, tags, and everything works fine.

However, when I try to open a branch in my browser or open a PR, I get the famous "Unsupported git service". I tried setting

```YML
services:
"github-work": "github.com"
```

in my config file but have had no luck :(

### To Reproduce
Steps to reproduce the behavior:

1. Define multiple SSH profiles in you `~.config/ssh`
2. Clone a repo using one of the aliases you created
3. Try opening a PR
4. See error

### Expected behavior
Lazygit should resolve the local url using the ssh alias (since that is how Git works). Or at least provide a way to set it up to mirror its behaviour.
