Build/Test Tools: Regularly run the html-api-html5lib-tests.

In [58010], the external test suite from `html5lib` was imported to validate the tree-construction steps in the HTML Processor to ensure that they are behaving according to the HTML specification.

The test group was excluded by default because there are a high number of skipped tests. The number of skipped tests has come down, but the group does not need to be run on every job.

This introduces a new job in the PHPUnit workflow for regularly running these tests on their own using the changes in [59251[.

Props desrosj, jonsurrell, jorbin, dmsnell, costdev, chaion07, engahmeds3ed.
Fixes #61209.
