Migrate to Google Analytics 4

[lunaleaps]

Description

Google Analytics is sunsetting older versions than 4 https://blog.google/products/marketingplatform/analytics/prepare-for-future-with-google-analytics-4/ by July. 2023.

From similar issue in docusaurus from @slorber

Analytics data will not be migrated to the new system

For sites that want to migrate to Analytics 4 and keep historical data, they can run both analytics side-by-side so when the former analytics system is shut down, they have enough historical data

For these reasons, we should not wait until the final deadline to support Google Analytics 4 and allow sites to seamlessly/incrementally migrate to Analytics 4.

Task

Can someone take point on figuring out how to get us ready for GA4?
