### What happened?

Contrary to what is shown on this page: https://docs.litellm.ai/docs/tutorials/claude_code_plugin_marketplace it is not possible to add skills that reside in a repository other than github. For some reason, the field where to input the URL is named "GitHub URL" and only accepts a Github URL.

### Steps to Reproduce

1. Go to your litellm instance /ui/skills/ 2. Input a URL like https://username:password@mygitlab.com/common/skills.git 3. A error says "Please enter a valid GitHub URL"

### Relevant log output
