Clarify the reason for always using the React provided client

[joshua-clarify]

Is your feature request related to a problem?

In the PostHog React docs, it mentions you must use the PostHog provided client

However, looking at PostHogProvider and usePostHog, all it does is return the global initialized client.

Use case: we would like to be able to track events in and outside of React.

Describe the solution you'd like

Please clarify in the docs whether it is safe to just import the global client if we handle initialization.

Describe alternatives you've considered

Why is a hook even necessary?

I'm also curious about this.

It would very convenient to know I can safely call posthog methods outside the React context.
