Remove usages of EDX_API_KEY

[asadali145]

Open edX is going to remove the EDX_API_KEY. Details can be found at openedx/edx-platform#34039. We have a couple of stale usages that we want to remove. We are using the EDX_API_KEY with the token authentication and we can safely remove EDX_API_KEY as per initial R&D.

Here are the usages:

• mitxpro/courseware/api.py

  Line 134 in 3efb080

  API_KEY_HEADER_NAME: settings.OPENEDX_API_KEY,

• mitxpro/courseware/api.py

  Line 520 in 3efb080

  {"access_token": auth.access_token, "api_key": settings.OPENEDX_API_KEY},

• mitxpro/courseware/api.py

  Line 539 in 3efb080

  "api_key": settings.OPENEDX_API_KEY,

Acceptance Criteria:

• Usage of EDX_API_KEY is removed
• No impact on any of the features or management commands

@mudassir-hafeez Could you take a look at this? I think @Anas12091101 's xPRO integration isn't working so it might be a good idea to take this on at this point.
