block: when doing an arbitration enforcement (AE) partial block, mention the partially blocked pages in the user talk template

[NovemLinguae]

Requested by Daniel Quinlan on Discord

What

• When partially blocking someone for arbitration enforcement (AE) reasons (basically any time Twinkle places Template:Uw-aepblock), make sure to include the parameters |partial=yes and |area=[list the pages here]

Why

• This causes the partially blocked pages to display in the user talk page block message, which is clearer for everyone

Notes

• See the template documentation at https://en.wikipedia.org/wiki/Template:Uw-aepblock#Usage
• {{subst:Uw-aepblock|topic=a-a|partial=yes|area=[[Test]]}} will render...
  
• make sure pblocking multiple pages also renders correctly. might need to convert an array of pages to a human readable, comma separated string that includes the word "and"
