luci-app-upnp: restore translations: ACL, intro

[stokito]

Fixes for the #7407

@systemcrash please merge before conflicts

[systemcrash]

Merged - thanks for the quick fixes @stokito

[Self-Hosting-Group]

This restores errors...For example, ACLs and not ACL.

[systemcrash]

Minor. i18n people may fix if it's deemed weird, on the next pass.

[stokito]

Yes, the Weblate will show such strings as "Needs for a review"

[Self-Hosting-Group]

Just seen: IPv6 hint not in ACL text. (IMHO, when it comes to security, e.g. with an ACL, the "IPv6 always allowed" hint is actually still important)

[stokito]

It's in templates/upnp.pot file but here we just have outdated translations without the the hint yet translated.

Well, there is a new Weblate conflict thanks to these changes from outside Weblate...

Weblate is really picky if changes are done while it has commits with translations to the same strings.
