MangaDex: Scanlation Group blocking (#10376)

* Add (somewhat) working group blocking

blocks an input scanlator group
doesn't seem to block official/external-link groups

* Fine tuning adjustments*

 - sanitise inputs as much as possible
 - add to summary a bit more
 - `setDefaultValue` looks to set once and never again. So even if
   EditText receives an empty String, it is still valid...
   Not sure if I could do it better

* Increment mangadex.extversioncode
