Update google-analytics-4.md Airbyte GA4 link

I noticed the airbyte docs link goes to the archived GA Universal Analytics link, rather than the GA4 page, updating.

(note their URLs are out of step - https://docs.airbyte.com/integrations/sources/google-analytics-v4/ goes to UA, https://docs.airbyte.com/integrations/sources/google-analytics-universal-analytics is page not found, and https://docs.airbyte.com/integrations/sources/google-analytics-data-api is the GA4 link)
