Automatic Metrics API

[jukent]

Closes #319

Adds:

• necessary extensions to the conf file
• a Python script that accesses the secrets for each GA4 property and writes to a json file if there are more than 100 new users
• a Python script that writes the metrics.md file from this json (can easily be edited to display charts and things)
• a GitHub action that runs this script weekly and pushes the changes
• adds this metrics page to the about section of the footer-menu

There are new secrets for each GA4 properties ID and for the credentials file.

Here is the list of additional dimension and metric keys.

Just for reference - the limit to API requests a day is 50,000. I think that is large enough that we don't have to be concerned. Just documenting that here for posterity.

After talking to @anissa111 and @brian-rose, I'm going to edit this action to be within the nightly build - editing it to update the metrics.md file and deploy the site. This way no commits and bot permissions are needed. Thank you for this elegant solution!

Relevant PR for adding deployment to nightly builds.

Some actions are in the cookbook-actions repo and others are within the portal. I'll have to take stock of the best place to add this. Since it is unique to the portal, I think it can live here in its own file, and have that file be called up as a job within the nightly build.

Added the deploy to nightly-build. Added automate-metrics to nightly-build, trigger-site-build, and publish-site, but not to trigger-preview.

Closing this because with the curl grabbing from my main branch I have to remember to change things on the branch and on main. I'm going to make a new PR from main
