"mr create" does not work with GitLab host that uses relative/sub-path
### Checklist
- [x] I'm using the latest version of the extension (Run `glab --version`)
- Extension version: tested `glab 1.62.0 (1df2df0d)` & `glab 1.61.0 (ef3ade5e)`
- [x] Operating system and version: See [OS env below](#environment)
- [x] ~~Gitlab.com or~~ self-managed instance
- [x] GitLab version (if self-managed) v17.8.0 ([customer](https://gitlab.zendesk.com/agent/tickets/638821)) & v16.11.10 (me)
- [x] I have performed `glab auth status --hostname …host…/gitlab` to check for authentication issues
```
$ glab auth status --hostname …host…/gitlab
…host…/gitlab
✓ Logged in to …host…/gitlab as root (/Users/katrinleinweber/.config/glab-cli/config.yml)
✓ Git operations for …host…/gitlab configured to use https protocol.
✓ API calls for …host…/gitlab are made over https protocol.
✓ REST API Endpoint: https://…host…/gitlab/api/v4/

```
- [x] Run the command in debug mode (like `DEBUG=true glab mr list`) and attach any useful output
```
$ DEBUG=true glab mr create

### Summary
Although [we fixed a related issue](https://gitlab.com/gitlab-org/cli/-/issues/1168), there there still seems to be a bug related to recognizing the relative/sub-path in the local `git remote` configuration.
### Environment
- OS: Darwin 24.5.0 arm64
- SHELL: /bin/zsh
- TERM: xterm-256color
- GLAB: glab 1.62.0 (1df2df0d)
### Steps to reproduce
1. Configure a GitLab test instance with `external_url '…host…/xyz'`
2. `glab auth login --hostname …host…/xyz` :ballot_box_with_check:
3. Clone a test repo via HTTPS, create new branch & commit
4. `glab mr create`
### What is the current _bug_ behavior?
```
Could not create recovery file: none of the git remotes configured for this repository point to a known GitLab host. Please use `glab auth login` to authenticate and configure a new host for glab.
Configured remotes: …host…ERROR: none of the git remotes configured for this repository point to a known GitLab host. Please use `glab auth login` to authenticate and configure a new host for glab.
Configured remotes: …host… ### WITHOUT the expected `/gitlab !!!
```
### What is the expected _correct_ behavior?
The same as when ``external_url '…host…'` without relative/sub-path were used:
```
$ glab mr create

### ~~Relevant logs and/or screenshots~~
### Possible fixes
I noticed that `git config --get-regexp ^remote\..*\.glab-resolved` from the `DEBUG=true` output fails, but `git config --get-regexp '^remote\..*\.glab-resolved'` works. ~~So, would it be as simple as inserting the `'`: [remoteCmd := exec.Command("git", "config", "--get-regexp", `'^remote\..*\.glab-resolved$'`)](https://gitlab.com/gitlab-org/cli/blob/v1.62.0/internal/git/git.go#L354)~~ Nope: Same error as above, after successful compilation of that change.
