Optional FAQ section for plugins

It would be interesting if as part of auto-generated page for each plugin, we had zero or more FAQ entries that are also populated from YAML.

This occurred to me as a follow-on from this Slack thread https://meltano.slack.com/archives/CMN8HELB0/p1638869197146700?thread_ts=1638869197.146700&cid=CMN8HELB0 where a user was able to solve their connection problem to Atlas following a recommendation given in a GitHub issue: https://github.com/singer-io/tap-mongodb/issues/42#issuecomment-866379009.

It's not exactly a bug in the tap itself but rather how to make it work with a hosted provider of the source. There may be similar recommendations for Postgres on RDS, etc.
