[Feature request] Add "Ctrl+Y" as an alternate shortcut for "Redo" in Kate
When editing text, you can undo a change you made with Ctrl+Z; you can then apply the change again (undoing the undo) with Ctrl+Shift+Z; this is standard stuff.
However, many users don't know the Ctrl+Shift+Z shortcut, and usually type "Ctrl+Y" to redo a change. It's the shortcut you see in the edit menu of Miscrosoft Word and LibreOffice Writer, for instance. That shortcut is also available in Firefox, Chrome, VsCode, Notepad++, etc.
(Though I think most editors support both shortcuts.)
Also, as far as I'm aware Ctrl+Y currently doesn't have a default assignation. As such, I think it would be worth assigning it as the alternate shortcut for the "Redo" command.
