Regenerate fomantic lockfile and build it with our browserslist (#29560)

1. Make fomantic build use [our
browserslist](https://github.com/go-gitea/gitea/blob/e3524c63d6d42865ea8288af89b372544d35474b/package.json#L99).
I found no other way than to sed-replace into it's js, the normal
browserlist config files do not work. The effect of this change is the
removal of some uneeded CSS vendor prefixes.
2. Regenerate `web_src/fomantic/package-lock.json`, this might shut up
some security scanners.
