feat: implement room state retrieval and

conditional avatar update

Introduces a new method `get_state_event` to asynchronously retrieve
state events for a given room and event type, enhancing the bot's
ability to fetch specific room states before performing actions. This
functionality is leveraged to conditionally update room avatars only if
they are not already set, reducing unnecessary updates and improving
efficiency. Additionally, the commit includes minor formatting
adjustments for better code readability.

Refactoring the avatar updating process to assess the current state
before action prevents redundant network calls and aligns with optimal
resource usage practices, contributing to a smoother operation and
potentially reducing the workload on the server.
