Migrate to Google Analytics 4 (GA4)

[chalin]

This issue is part of a CNCF-wide effort to upgrade project websites to GA4 since Google has deprecated Universal Analytics (UA). For more details, see:

• https://github.com/cncf/techdocs/issues/108, including reference to a suggested migration process, which we've used to migrate a few CNCF projects already.

Tasks: stage 1 (no code or config changes necessary)

• [x] Create a GA4 site tag under the CNCF projects account using the GA4 migration assistant. The new GA4 stream measurement ID is: G-K9DYZWQ75Q
• [x] Connect the GA4 ID from the UA ID
• [x] Confirm that the GA4 site tag is receiving events
• [x] Confirm that the UA site tag is still receiving events

Tasks: stages 2 & 3 (possibly later)

• [x] Connect the UA ID from the GA4 data steam
• [ ] Configure GA4 ID either through:
  • [ ] Netlify snippet injection, or
  • [ ] Using the existing config param googleAnalyticsId - #340
• [ ] Confirm that the GA4 site tag is receiving events
• [ ] Confirm that the UA site tag is still receiving events

Cleanup

• #327

Question for maintainers: is the website hosted by Netlify? If so, can you grant me access to the Netlify account?
