media: docs: Remove extraneous \endgroup from P010 table

The \endgroup command at the bottom of a table added in commit
5374d8fb75 ("media: Add P010 video format") doesn't have a
corresponding \begingroup command preceding it.

This imbalance causes an build error in "make pdfdocs".

Fix the issue by removing it.
