fix: Add json_tags_id_uppercase functionality to the JSON style PascalCase

[Lingkar]

I was having trouble with the json_tags_id_uppercase config with the pascal json tag style.

When the json_tags_id_uppercase is set to false I expected the json output to be:
user_id -> UserId , however resulted in UserID
id -> Id , however resulted in ID

If my undertanding of the config was incorrect, please let me know.
