Add Mapbox key to superset

[bendnorman]

• Add Mapbox key to superset deployment so we can see maps!
• Give the usage-metrics-archive service account permissions to get bucket information

Testing

How did you make sure this worked? How can a reviewer verify this?

• Can you see the map on the s3 dashboard?
• Make sure Ella's github action doesn't hit a permission error.

To-do list

Preview Give feedback

1. If updating analyses or data processing functions: make sure to update or write data validation tests (e.g. test_minmax_rows())
2. Update the release notes: reference the PR and related issues.
3. Run make pytest-coverage locally to ensure that the merge queue will accept your PR.
4. Review the PR yourself and call out any questions or issues you have
5. For minor ETL changes or data additions, once make pytest-coverage passes, make sure you have a fresh full PUDL DB downloaded locally, materialize new/changed assets and all their downstream assets and run relevant data validation tests using pytest and --live-dbs.
6. For bigger ETL or data changes run the full ETL locally and then run the data validations using make pytest-validate.
7. Alternatively, run the build-deploy-pudl GitHub Action manually.
