Backporting a driver into one of the stable trees is not a sanctioned activity. Stable kernels only get fixes for bugs, not new features such as a complete driver. At least one distro packages rtw89 as kernel modules the same as my GitHub repo. That distro is openSUSE, which gets its source from that very repo. There may be others that provide similar packages.
