fix: create_camunda_cloud_channel

[felicijus]

Fix create_camunda_cloud_channel, current and deprecated functions.

Changes

1. audience should be static Camunda Docs
   audience="zeebe.camunda.io
2. scope should either be None (Optional parameter), because setting it to the cluster_id also works. Maybe relevant for enterprise user with custom scope configs...
3. leeway and expire_in i don't really know if there is need for customization. Would not hurt to keep I guess.

#510 Is an import error, where the old create_camunda_cloud_channel function was used. (The old function also needs a static audience)
