What

Adds contrib/**/* in the changes: clause for the oc.misc_checks job (compare this with that).

I also remove a template that is no longer used.

Also shellchecks and shfmts the script contrib/ai-simulator/script-scrap-weeklynet.sh that snuck by in the meantime.

Why

I messed up in !12490 (merged) and accidentally removed this line.
