fix: fix issue with validateRecord not validating bsky posts

post.record is a json object and its strings aren't typed. ValidateRecord
requires there to be a `BlobRef` type on the thumb field. Since there wasn't,
the validation failed.

jsonToLex will type our json string so instead of an untyped Object for the thumb
field, it will now be a BlobRef.
