Based on the recent discussion on the debian-fonts mailing list and the resulting
update of the wiki, the severity of font-in-non-font-package should be increased
from info to warning.

The text of the tag should also be updated to match what the test is currently
checking. Specifically, it adds information regarding WOFF, WOFF2, and EOT fonts.
There is an MR to implement these changes:
