Replace references to Google Analytics with Posthog where relevant (#10868)

* Swapping out sentence about Google Analytics with a PostHog version of it.

* replace "Google Analytics" with "Netdata"

replace "sent to Google Analytics" with "sent to Netdata". 

Since we are no using a self hosted Netdata PostHog instance i think "sent to Netdata" makes most sense.

* update opt-out paragraph based on posthog

* Replace references to Google Analytics with PostHog

@joelhans @cakrit i'm assuming with might need to have legal input on any changes to this doc so my changes may or may not be acceptable, at a minimum they need a review by someone from legal.

* update google analytics reference with posthog

* replace google analytics with posthog
