[kaustavb12]

Description

Currently the default certificate template breaks during rendering if GOOGLE_ANALYTICS_4_ID is defined, because of a missing import.

This PR fixes this issue.

Testing instructions

1. Login to this sandbox using the default credentials openedx/openedx.
2. Go to the instructor tab of the demo course and open the network tab in developer tools of your browser to check calls to googletagmanager.com with the dummy id GTM-ABCD123. This verifies that GOOGLE_ANALYTICS_4_ID is configured correctly for this sandbox.
3. Go to the certificates page in Studio for the demo course and click on Preview Certificate.
4. Verify certificate with the default template is rendered correctly.
