fix(medusa): List products by type_id (#2427)

**What**
- Fixes `GET /products` in both admin and store API so they no longer accept the param `type?: string`, but instead accept `type_id?: string[]`

**Why**
- Filtering by type would never return any products as `ptyp_:id` !== `ProductType`.

**Testing**
- Added an integration test for each endpoint.

Closes CORE-695
