fix: update jhipster.github.io page for application upgrade to 8.0.0

@mraible @mshima I think this page needs more work. It's dated as is even with my updates (which may only raise awareness). I could not get jhipster update to complete on a fresh JHipster 8 project even to 8.1.0 on Node 18. I had to resort to what I call the "Raible Forced Diff" method:

cd project
rm -rf *
vi yo-rc.json # s/8.0.0/8.1.0
jhipster
git diff # or git status; git restore or other diff tooling.
