Document how to map between ICNs and UUIDs in the rails console

[JonathanKamensDVA]

Description

We have recently updated our PII guidelines to explain to people how they're allowed to use ICNs, specifically that they shouldn't be logging them to Datadog and should be logging the account UUID instead. We're now getting questions from people about how they can map back and forth between ICNs and UUIDs when they need to do that.

The answer appears to have come from the Identity team:

use UserAccount.find_by(icn: <icn>) or UserAccount.find_by(id: <uuid>)

@jperk51 and @timwright12 suggested that it would be a good idea to document this somewhere in the platform docs. I agree with them. ;-) They suggested putting it on the page that talks about other techniques for interacting with the rails console. I think we should then add a reference to that from the recently added ICN guidelines.
