Block Patterns: Add category for banners (#44203)

* Block Patterns: Add category for Headings & Titles

Fixes #40116

With this new category, we can clariy the classification of patterns as
"Headers". Category "Headers" pertains to global patterns meant to sit
at the top of a page, while category "Headings & Titles" pertains to
typically visually distinctive elements that help structure the contents
of a page.

* Rename to "Banners"
