In documenting the changes for MONGOSH-199, I noticed that .help() does not work for the following BSON classes:
- `bsonsize`
- `MD5`
- `UUID`
- `HexData`
For example, MD5.help() returns TypeError: MD5.help is not a function
Very minor, but would be nice if we could get the .help() methods for those supported at some point as well!
