We would never update or build fomantic again, we have forked it as a
private library long time ago.
So just put the JS and CSS files in "fomantic/build" into git. And use
"import" to use them.
Remove "form.js", rewrite "tab" component.
All source code is from official Fomantic UI build. Will apply patches
in separate PRs.
None of the frontend js/ts files was touched besides these two commands
(edit: no longer true, I touched one file in
61105d0618
because of a deprecation that was not showing before the rename).
`tsc` currently reports 778 errors, so I have disabled it in CI as
planned.
Everything appears to work fine.
