"This page says ..." - Which page?

The kernel family that you get installed depends on the kernel meta-package(s) that you have installed.

With the meta package linux-generic you get the 5.15 kernel family.
With the meta package linux-generic-hwe-22.04 you get the kernel family of Ubuntu 22.04 which (currently) is 5.19

see https://launchpad.net/ubuntu/+source/linux
and https://launchpad.net/ubuntu/+source/linux-meta-hwe-5.19

Which kernel meta package(s) do you have installed?
dpkg -l | grep linux-generic
