Allow Global auto connect for kde-frameworks-5-99-qt-5-15-7-core20

I’d like to also request global auto connect be allowed for the content snap kde-frameworks-5-99-qt-5-15-7-core20

It is used to build Qt and KDE Snaps and e…g Krita is currently out of date because it can’t be built now until the global auto connect is allowed.

It will be used by the kde-neon extension which is used by a few Snaps.

A previous request

+1 from me - this is a well-established pattern for KDE snaps.
