Additional Information

Hi maintainers! 👋

I'm requesting a shortcode for this repository to make it easier for users to add it in CloudStream.

Repository Details:

• Name: AMSC-FR (Mourad's French Repo)
• Language: French
• Description: CloudStream French providers/plugins repository
• Repository URL: https://raw.githubusercontent.com/mouradchaouche/cloudstream-frenchrepo/main/repo.json

Requested Shortcode: amsc-fr

This would allow users to simply enter amsc-fr when adding a repository in CloudStream, instead of having to remember the full URL.

Would you be able to support this? If shortcodes need to be hardcoded in the app, I understand. Otherwise, please let me know if there's a shortcode mapping system I should use.

Thanks! 🚀
