[BUG] Text should be replaced by an icon on "Manage livestream" page

[xannyxs]

Describe the bug On the "Manage livestream" page, there is currently a short text saying "(youtube)" next to the multistream option. This text should be replaced with an appropriate icon to improve the user interface and consistency with other parts of the application.

To Reproduce Steps to reproduce the behavior:

1. Go to /studio/{organizationSlug}/
2. Click on "manage"
3. Make a YouTube multistream
4. Observe the "(youtube)" text instead of an icon

Expected behavior Instead of the text "(youtube)", an appropriate YouTube icon should be displayed. This would improve the visual consistency and make the interface more intuitive.
