False positive: `PronounKnew` flags "anyone new"

> before inviting anyone new in.

This can probably be fixed by not flagging after so-called "indefinite pronouns". Those are currently not marked in the dictionary. Perhaps the same can be achieved by checking if the word before "new" is a "personal pronoun", which can currently be queried.

Start by locating the PronounKnew rule and the dictionary entries it uses, then inspect how personal pronouns are queried. Reproduce the "anyone new" example and confirm that it is no longer flagged while the rule still catches its intended cases.
