Customize: Remove Vimeo reference from description for external header videos.

Vimeo's API requires a Pro account to display videos as background videos
(i.e., without player controls), thus we shouldn't support Vimeo
URLs by default in custom header videos. This removes the reference of Vimeo
from the control description in the customizer.

Fixes #38544.
