Unsupported git service (after renaming remote name)

**Describe the bug**
My setup used to work, so when I pressed `o` to open an MR with GitLab, but since I renamed the remote from `origin` to a different name, I get this error now.

**To Reproduce**

1. Clone the repo
2. Add 2nd remote (my fork)
3. Rename `origin` to something else
4. Try to create MR with `o`

```yaml
services:
'gitlab.exmaple.com': gitlab:gitlab.example.com
```

**Expected behavior**
The MR url should open in my default browser

**Version info:**
```
❯ lazygit --version
commit=611fabde11d24d9acc71ee26077b9a1101f59f27, build date=2024-09-18T10:56:10Z, build source=binaryRelease, version=0.44.1, os=linux, arch=amd64, git version=2.47.0

❯ git --version
git version 2.47.0
```

**Additional context**
When I run lazygit with `-debug` in the logs output, I still see lazygit try to use the origin remote name
