Subject: [PATCH] feat(presidio): annotate the analyzer-result locals the token
 suffix reads

entity_type and value come out of an untyped analyzer mapping. They only fed
an f-string before, where an Any costs nothing; passing them to
_stable_token_suffix makes them call arguments, which is what the remaining
unknown-argument error was.
