Ubuntu freezes package version number (with only few exceptions like browsers) when they release a new version.
You will either need to wait for a new version (most likely 23.10) or use 3rd party maintained PPAs.
Ubuntu 22.04 has ray tracing support for AMD RX 6000 graphics cards, but the performance is terrible. You can install Mesa 23.1 from a PPA and it will work much better. Be sure to take a backup in case something breaks and you need to revert to the stock version. I had some trouble getting the 32 bit Mesa libraries to install, which are required for Steam.
I can run Quake II RTX at 50-60 fps in 1080p on my RX 6700 XT using Mesa 23.1.3 and Linux kernel 5.15.
I can run quake rtx but not cyberpunk or blender hip RT, I guess I'm just gonna wait until ubuntu releases a new mesa update
If using steam, there's a steam snap project that also aims to upgrade mesa stack more, so that can use newer stack to play with 22.04 host installation.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
