Also add top-level description field. The celpolicy parser has special handling for CEL expressions embedded in the YAML document in order to preserve location information. This is used to help the CEL compiler correctly highlight error location. As a consequence, the CEL expression will include characters that are normally not considered meaningful in YAML, and the literal and folded style for multiline strings are treated identically.
