fix(Revert): changed back to json type instead of jsonb

Since most operations will be simply reading and writing json data to the info field of the Info
table, storing a jsonb format takes up a slightly more space and must be transformed to text during
reads. Since most features simply read the entire field, using the json format makes more sense than
jsonb
