runtime(html): Restore HTML syntax file tests
Rendered element content results in test failures on macOS and FreeBSD.
The included content for these elements was incidental to the primary
intent of the test to check element tag highlighting so set
g:html_no_rendering to disable content rendering.
FreeBSD fails for even an empty <strike> element.
See #13591 and #14215.
closes: #13595
