HTML API: Remove empty test file after adding support for missing ele…

…ments.

When support was added for the remaining tags in the IN BODY insertion mode, a test
file indicating that support was necessary for certain parts of the parser was
removed, but it wasn't removed from SVN when sending over the patch from `git`.

This patch removes that empty file so that the WPCS workflows pass.

Discussed in https://core.trac.wordpress.org/ticket/61576

Follow-up to [58779].
