Ensure page feedback works under GA4

[chalin]

Followup to #972. Since the Falco website has custom page-feedback code, that custom code will need to be updated to work with GA4.

Tasks

• Send page feedback using gtag #994
• Delete the previously added event-modification rule
• Confirm that page_helpful events are bring sent to the CNCF GA4 data stream
  For details, see the comment below

(The following old issue text isn't relevant. Keeping it for reference.)

If you'd like to make it easy to see page-feedback events under GA4, you'll need to setup an event-modificaiton rule. For details, see:

• Page feedback: support for Google Analytics 4 (GA4) google/docsy#1302 (comment)

You can also track that issue for the status of a proper fix in Docsy.

@aijamalnk @LucaGuerra @leogr - let me know if the Docsy page-feedback feature is something that you've been actively using or not. I can help setup the event-modification rule.

@chalin we do want to have the page-feedback events after the migration. Could you please help us to set up the event-modification rule? Thank you!

But it isn't processing events. I'll investigate shortly.

After deleting the previously added event-modification rule, I've confirmed (using https://tagassistant.google.com), that page_helpful events are being received by the CNCF GA4 data stream:
