[Enhancement]: Support for GitLab Duo

[CraigsOverItAll]

Before Requesting

• [X] I have searched the existing issues, and there is no existing issue for my feature request

What feature do you want?

Are there any plans to support GitLab Duo?

Ref:

• GitLab Duo docs
• VSCode Plugin

There is no plan at the moment but I think it's possible given that they are providing a Neovim plugin that contains a language server.

I will give it a try when I have time.

If anyone else would like to implement it as a Copilot for Xcode extension, please let me know.
