Unable to opt out of streaming

Describe the bug Based on the docs here:

In the React SDK, streaming mode is enabled by default. To disable streaming mode, specify a streaming: false attribute in your options object.

I should be able to pass streaming: false in the options field to avoid rerendering upon new updates.

To reproduce Steps to reproduce the behavior.

Initialize app using withLDProvider. I imagine this behavior may be present with other methods of initializing as well.
- Ensure streaming: false set in options object.
```
const LDProvider = withLDProvider({
clientSideID,
user,
options: {
streaming: false
}
})(({ children }: { children: Node }) => BrowserProvider({ children }));
```
Change a flag in the LaunchDarkly dashboard and see the app rerender despite the streaming setting. You can easily check this by console logging out useFlags() in a component and see it log out with the updated values upon changing a flag.

Expected behavior I expect the option streaming: false to turn off live flag updates per JS SDK docs.

Logs N/A

SDK version 2.24.0

Language version, developer tools node v14.15.0, Chrome 97.0.4692.99

OS/platform macOS Monterey 12.1

Additional context Initial hunch makes me think we should be checking to see if streaming is enabled here before running subscribeToChanges.
