python user guide broken

Bug Report

See https://perspective.finos.org/docs/python/, specifically the Torando websocket example index.html:

<perspective-viewer id="viewer" editable></perspective-viewer>

<script>
    window.addEventListener("DOMContentLoaded", async function () {
        // Create a client that expects a Perspective server
        // to accept connections at the specified URL.
        const websocket = perspective.websocket(
            "ws://localhost:8888/websocket"
        );

        // Get a handle to the Table on the server
        const server_table = websocket.open_table("data_source_one");

        // Create a new view
        const server_view = await table.view();

        // Create a Table on the client using `perspective.worker()`
        const worker = perspective.worker();
        const client_table = await worker.table(view);

        // Load the client table in the `<perspective-viewer>`.
        document.getElementById("viewer").load(client_table);
    });
</script>

Of course, table is not defined.
Worse, server_table.view() is not a function.

Solution

The Tornado example works. Hard problem to keep the web guide snippets in sync with fast-moving codebase, for sure. But here's the details:

Specifics

1. add worker in the guide
2. await the open_table
3. server_view from server_table, not table
4. worker.table isn't a future
