Patch fomantic-ui to workaround build issue (#11244)

* Patch fomantic-ui to workaround build issue

Better workaround than https://github.com/go-gitea/gitea/issues/10653
for https://github.com/fomantic/Fomantic-UI/issues/1356. It does not
seem like we're getting a new Fomantic-UI release anytime soon, so
this patches it after node_modules installation.
