BLOSSOM-290 enables UI 6 definition usage in dialog/tab factories. 

While we are noting it in a new section called "6 UI definitions of dialog and tab factories" on https://docs.magnolia-cms.com/product-docs/6.2/Modules/List-of-modules/Blossom-module.html

(https://git.magnolia-cms.com/projects/DOCUMENTATION/repos/product-docs/pull-requests/1012/diff#modules/ROOT/pages/Modules/List-of-modules/Blossom-module.adoc)

it would be beneficial to showcase 6 UI-native definitions also further below on the page (and maybe side-by-side to the existing 5 UI code?).

Provide the 6 UI definitions, append a commentary if needed.
