Point Documentation link from support dropdown to HelpHub

[Kenshino]

Current the dropdown for Support on WordPress.org has Forums and Documentation.

Documentation is pointed still to Codex which we're deprecating. We've launched HelpHub and the Documentation link should point to HelpHub which is at wordpress.org/support

I would appreciate some help changing the link.

So should it remain a separate link if it goes to the same place as Support? If so, should it be first, like other places where the first item is the same destination as the Top Level item?

(an example would be in the admin: Appearance and Themes, or Settings and General, or Media and Library)

Fixed in [14756-dotorg].

The link URL was changed as suggested, and also moved to be the first link in the submenu.

Reopening as this is also required for the Trac header when viewing from:
•​https://core.trac.wordpress.org/ or https://meta.trac.wordpress.org/

Patch incoming...

In 8165:

Trac: Header: Change Documentation submenu link (of Support) to point to HelpHub home instead of deprecated Codex.

Props netweb.
Fixes #4041.
