docs: Fix Python Actor configuration property naming

[tducret]

Updates Python code examples to use the correct Actor.configuration property instead of Actor.config that got
removed in the Python SDK v3 (see https://docs.apify.com/sdk/python/docs/upgrading/upgrading-to-v3#removed-actorconfig-property).

---

Note

Updates Python code samples to use Actor.configuration (web_server_port, standby_port, meta_origin, token) instead of removed Actor.config across Standby and environment variables docs.

• Docs (Python examples):
  • Standby mode (sources/platform/actors/development/programming_interface/actor_standby.md):
    • Use Actor.configuration.web_server_port and Actor.configuration.standby_port in HTTP server examples.
    • Check Actor.configuration.meta_origin for Standby mode detection.
  • Environment variables (sources/platform/actors/development/programming_interface/environment_variables.md):
    • Access and set token via Actor.configuration.token instead of Actor.config.token.

Yes, but this is probably beyond the scope of this PR. A good example is readthedoc, which usually provides the documentation per a given app version. Not sure how you want to address that with your documentation stack.
