30 Days Developer Challenge - Day 12 - `collection_uid` set as environment variable in `Postman API env`

In the collection named Day 12: Postman API, collection_uid is set as environment variable when creating the environment named Postman API env as part of the day’s challenge. This restricts a user from setting the collection_uid as a collection variable to be used in submit request inside Submit your solution folder for all upcoming days’ challenges Postman API env is to be used.

This restriction is due to the scope of variables where an environment variable overrides the collection variable.

For an instance, in Day 13: Newman, the submit request uses the Postman API env as the environment which has a variable named collection_uid. The value of this variable corresponds to Day 12: Postman API collection. Thus, a user cannot set a collection variable collection_uid in Day 13: Newman collection because the environment variable will always take precedence. If not done so, the test cases will fail. In such a case, the user cannot use the request URL https://api.getpostman.com/collections/{{collection_uid}} and instead has to type in the entire collection ID in the request URL as a string literal.

Can we change the documentation of Day 12: Postman API to set collection_uid as the collection variable instead of environment variable?
