Remote "linux-lts" and "linux-latest" from kernel selection

Hi,

I tried to select linux-latest but the installer told me it's not available. Searching for it I found https://forum.manjaro.org/t/updated-linux-latest-and-linux-lts-packages/57264 -> looks like both packages where removed.

The fix would be to remove the options from here:

• https://gitlab.manjaro.org/applications/manjaro-architect/-/blob/master/lib/util-base.sh#L215
• https://gitlab.manjaro.org/applications/manjaro-architect/-/blob/master/lib/util-desktop.sh#L261
