[BUG]: aws-data-api driver serializing jsonb to string on read and write paths

### Report hasn't been filed before.

- [x] I have verified that the bug I'm about to report hasn't been filed before.

### What version of `drizzle-orm` are you using?

0.44.2

### What version of `drizzle-kit` are you using?

0.31.2

### Other packages

drizzle-orm/aws-data-api/pg

### Describe the Bug

- Undesired behavior:
- When querying from an RDS instance using the `aws-data-api/pg` driver, jsonb columns are read as strings, even if they are written as jsonb objects.

- Steps to reproduce:
- Write a jsonb object to the database with a different driver (e.g.) bun-sql, then try to read using the `aws-data-api/pg` driver

- Desired Result:
- Drivers should return jsonb as objects. Drizzle types these jsonb reads as objects, and the driver should respect that.
