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:

• Migrate CNCF websites to GA4 cncf/techdocs#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)

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

Tasks: stages 2 & 3 (possibly later)

• Connect the UA ID from the GA4 data steam
• Configure GA4 ID either through:
  • Netlify snippet injection, or
  • Using the existing config param googleAnalyticsId - Use Google Analytics 4 (GA4) ID #340
• Confirm that the GA4 site tag is receiving events
• Confirm that the UA site tag is still receiving events

Cleanup

• Ensure that analytics is enabled only for production builds #327

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