DEV: support multiple capture groups for text post process

PERF: Move mention lookups out of the V8 context. (#6640) We were looking up each mention one by one without any form of caching and that results in a problem somewhat similar to an N+1. When we have to do alot of DB lookups, it also increased the time spent in the V8 context which may eventually lead to a timeout. The change here makes it such that mention lookups only does a single DB query per post that happens outside of the V8 context.
