Subject: [PATCH] feat(console): allow to configure PostHog (#9135)

# Which Problems Are Solved

The console has no information about where and how to send PostHog
events.

# How the Problems Are Solved

A PostHog API URL and token are passed through as plain text from the
Zitadel runtime config to the environment.json. By default, no values
are configured and the keys in the environment.json are omitted.

# Additional Context

- Closes https://github.com/zitadel/zitadel/issues/9070
- Complements https://github.com/zitadel/zitadel/pull/9077
