feat: 4106 nnnnat catalogItem GQL query

[nnnnat]

Resolves #4106
Impact: minor
Type: feature

Issue

Summary
Create a query to retrieve a single catalog product by the provided slug or ID.

Implementation
The catalogProduct query should have the following signature

catalogProduct(slugOrId: String): CatalogItemProduct

See #4105 for schema detail.

Acceptance Criteria
Using GraphQL, I can use the catalogProduct(slugOrId: String): CatalogItemProduct query to get a single CatalogProduct by it's slug.

Solution

• Created a Catalog Collection Query that returns the product from the catalog collection
• Created a catalogItemProduct GQL query that returns a CatalogItemProduct object
• Created unit test for both of the new query functions
• Created integration test for the CatalogItemProduct GQL query.

Testing

1. Spin up a fresh RC shop, login as an admin and create a few products and publish them to the catalog.
   • Note: if you use the reaction devtools to speed products you'll need to update your RC shop name to be "reaction swag shop" or you'll get an error from reaction. You may need to change the shop name from the DB because of this (Unable to update shop name, Promise.await is not a function #4202) issue.
2. From graphiql or localhost:3030/graphiql query a product by slug with catalogItemProduct(slugOrId: "example-product") { _id } and copy the returned ID
3. Try the query again this time with the ID instead of the slug catalogItemProduct(slugOrId: "opaqueID") { _id product { slug } }
4. The same product should return.

See one little comment and delete the yarn.lock file since this repo does not use yarn

id -> ID since this is end-user documentation

@aldeed I've removed the yarn.lock and updated the catalogItemProduct query comments
