When building an autoinstall config for interim Ubuntu releases (i.e. 23.04 lunar lobster), the hwe kernel flavor option causes the installer to fail when installing the kernel.

This seems to be because the installer tries to pulls the OS version number and append it to the package name for installation.

How to reproduce:
Create an autoinstall yaml which contains the following parameters

  kernel:
    flavor: hwe

Try to install an interim release with the given autoinstall

Expected result
The installer should select the appropriate kernel metapackage

What actually happens
The installer appends the OS version number to 'linux-generic-hwe-' and uses that as the package name.
For Ubuntu 23.04 Lunar Lobster, the hwe package name is still 'linux-generic-hwe-22.04' so causes the installer to fail.
