Update WebSocket implementation to use Gorilla WebSocket library

- Replaced the existing `github.com/coder/websocket` package with `github.com/gorilla/websocket` for improved functionality and compatibility.
- Adjusted WebSocket connection handling, including message reading and writing, to align with the new library's API.
- Enhanced error handling and logging for WebSocket operations.
- Bumped version to v0.20.0 to reflect the changes made.
