Previously, we rely on the behavior that the default branch of upstream xanmod repo is set to latest stable. It turns out there's some lagging issue now, so I decide to fetch the version from xanmod.org page.
And for consistency, I also change the LTS version fetcher to use xanmod.org (previously it's www.kernel.org).
Improve the logic to check Stable & LTS versions.
