Bug#1070845: godot: Update to newest upstream version 4.x

[Otto Kekäläinen]

Hi,

Quick update to this:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1070845

The Godot 4 package was in the Debian NEW queue
(https://ftp-master.debian.org/new.html) since January and finally got
reviewed by FTP Masters for the first time yesterday.

Unfortunately they had some feedback about the debian/copyright file,
and the upload was rejected. We will be doing a new upload but since
it is now end of April and Trixie freeze is on, there the new version
has no chance of being included in Trixie.

Trixie will ship with only Godot 3.6, but luckily it is at least the
latest in the 3.6 series.
