chore: disable string escaping in snapshots

[Josh-Cena]

Motivation

See prettier/prettier#12612. This will make the snapshots even more copy/pastable!

In addition, I've added strip-ansi to our snapshot serializer, so that when snapshotting console output we won't care about the actual ANSI coloring being applied.
