Fix issue with Option
serialization (#10705)
# Objective - Fix #10499 ## Solution - Use `.get_represented_type_info()` module path and type ident instead of `.reflect_*` module path and type ident when serializing the `Option` enum --- ## Changelog - Fix serialization bug - Add simple test - Add `serde_json` dev dependency - Add `serde` with `derive` feature dev dependency (wouldn't compile for me without it) --------- Co-authored-by: hank <hank@hank.co.in> Co-authored-by: Gino Valente <49806985+MrGVSV@users.noreply.github.com>
