Rename "Delete" Tab to "Trash"

[adrianbj]

Short description of the enhancement

Rename Delete Tab to Trash on the Page Edit form

Why would the enhancement be useful to users?

It seems inconsistent to call the tab "Delete" when it actually just moves the item to the trash. The page list action button is called Trash, so I think this should be changed to match.
