Mangadex: View all Manga by a Group (+handle group links) (#10060)

* search Manga from a group using their id

* add group deeplink support

* linting

* increment mangadex.extVersionCode

* respect `dexLang`

eg: MangaDex (EN) needn't show a group's non-EN releases

* you cannot use filters on chapter endpoint

fixes HTTP 400 while trying to filter on chapter endpoint

* rewrite to use /manga endpoint instead of /chapter

ends up removing a lot of stuff I had previously but that's a good thing

* add check for valid UUID

if a UUID wasn't being provided, then the group queryParameter wouldn't
work and end up throwing Error 400. Might as well prevent that
