feat(medusa, core-flows, types): Allow to update the rules from a shipping options (#7175)

**What**
Add support for the following operations
- update rules from the update shipping options end point
- update rules from the batch update end point

Also added some improvements, that can be revisited later
- Add a rule value normalizer, jsonb will transform the input value to a [primitive](https://www.postgresql.org/docs/current/datatype-json.html#JSON-TYPE-MAPPING-TABLE) when possible meaning that passing `"true"` will result in storing `true` and not the string. The normalizer takes care of that
