Update LinuxCNC 2.9.5 on debian 13

I don't know why there seems to be a dependency on an old Python3 version, I don't see that anywhere in the Debian config folder.

However, the debian package itself seems to have a broken python3 dependency. I'm on the latest Raspberry Pi OS Lite (which is basically trixie with a custom kernel and a few Pi-specific tools installed). Any particular reason for the arm64 package to want python3 < 3.12? amd64 one depends on 3.13, and so does linuxcnc-uspace 2.9.4 that comes with trixie.
 

It's possibly a consequence of the recent Pi .deb that I posted being built on Bookworm as I don't have a Pi running Trixie at the moment. 
The Debian package control files don't specify a version, but it is possible that a dependency is introduced by the configure step of the software build. 

I have a feeling that the package for the Pi in www.linuxcnc.org/dists/trixie might be the Bookworm package rather than one built on Pi/Trixie. I don't know how that happened at this point, I might just have been hoping that it would work and have now found out otherwise
