Only pass :request_id option to Refresh Stream

When rendering `<turbo-stream>` elements for broadcasting, **omit** the
`:request_id` partial-local variable.

When rendered partials utilize [Action View strict locals][], the extra
variable raises an error:

```
unknown local :request_id
```

By omitting the `:request_id` from the
`Turbo::Broadcastable#broadcast_rendering_with_defaults`, it isn't
passed as part of partial rendering.

Likewise, since `broadcast_refresh` never renders a partial, but instead
builds an empty `<turbo-stream action="refresh"
request-id="..."></turbo-stream>` element, the `:request_id` local
variable isn't necessary.
