fix(gitlab): Properly handle auth for Gitlab project avatars

[GabDug]

Hey 👋

Context

We've noticed that our Gitlab project avatars were not loading properly, even in 4.2.0.

Proposed fix

I believe it's because the URL in project.avatarUrl does not accept Gitlab tokens anymore.

Gitlab provides a ~new API to get a project's avatar, supporting the same authentication modes as other APIs. This API does not require authentication for public projects.

I've also removed gitlab.com from the list of domains never needing auth - to properly support private projects on Gitlab.com.

Validation

I've only tested this change on an internal Gitlab with public/private projects and on gitlab.com with public/private projects.

Have a great day!

Summary by CodeRabbit

• Bug Fixes
  • Improved handling of GitLab repository avatar images to ensure consistent image display.
  • Updated logic so that images from gitlab.com are now loaded through a proxy, enhancing reliability for private or protected repositories.

Walkthrough

The changes update how GitLab repository avatar URLs are constructed and handled in both backend and frontend utilities. The backend now computes the avatar URL based on the repository's ID and self-link, while the frontend removes 'gitlab.com' from its list of public hostnames, altering how image URLs are proxied.

Changes

File(s)	Change Summary
packages/backend/src/repoCompileUtils.ts	Modified avatar URL handling in compileGitlabConfig to compute image URL from project ID and host.
packages/web/src/lib/utils.ts	Removed 'gitlab.com' from public hostnames in getRepoImageSrc, changing image proxying behavior.

Poem

In the warren of code, a tweak to the link,
GitLab’s avatar now fresher than you think!
No longer public, the bunny decrees,
Images hop through proxies with ease.
With clever URLs and a backend fix,
The repo’s new face is shown in the mix!
🐰✨
