build: remove websocket support from deltachat-jsonrpc

WebSocket support is not used
and is not maintained. It still uses
outdated axum 0.7 version
and does not have any authentication.

Delta Chat Desktop has a new browser target
that implements WebSocket support on top
of stdio server, supports blobs
and is tested in CI.
