Help/About: Change the HTML `title` of Themes Screen and add related HelpHub Docs link.

This change replaces the title of the Appearance Themes Screen to make it consistent with the main heading of the screen and with other Admin screens. It also adds a link to the related HelpHub Documentation in the Help tab of the screen.

Props jdy68.
