Remove outdated hgroup disclaimer

[thibaudcolas]

Description

This reverts commit fbb5b30, and removes the problematic disclaimer about <hgroup> from the Content categories page.

Motivation

In #18530 in July 2022, the disclaimers were removed, but only from the hgroup page. I suspect the Content categories page was missed. Then in December 2023, #30856 copies the outdated note from Content categories back to the hgroup page. I don’t think that disclaimer should have been there on any page, per the description of #32213:

The <hgroup> element was recently significantly revised in the HTML specification. The warnings about its impact on the outline algorithm are no longer relevant, as the concept of the outline algorithm was removed from the HTML specification as well.

This PR simply removes outdated content, and replaces the remaining bits with content that is more inline with the current definition for the element.

Additional details

See WHATWG Sections – the hgroup element

See #11153 for the initial rationale on removing those disclaimers.
