Add ReactDOMClient to ServerIntegrationSelect (#28132)

## Overview

Branched off https://github.com/facebook/react/pull/28130

## React for count changing
### Before
These tests are weird because on main they pass, but log to the console:

```
We expected 2 warning(s), but saw 1 warning(s).
We saw these warnings:
    Warning: Expected server HTML to contain a matching <select> in <div>.
        at select
```

The other one is ignored. The `expect(console.errors).toBeCalledWith(2)`
doesn't account for ignored calls, so the test passes with the two
expected (the +1 is in the test utiles). The ignored warning is

```
Warning: ReactDOM.hydrate is no longer supported in React 18. Use hydrateRoot instead. 
```

So the mismatch is in the ignored warnings. 

### After

After switching to `createRoot`, it still logs:

```
We expected 2 warning(s), but saw 1 warning(s).
We saw these warnings:
    Warning: Expected server HTML to contain a matching <select> in <div>.
        at select
```

But the test fails due to an unexpected error count. The new ignored
errors are:

```
Error: Uncaught [Error: Hydration failed because the initial UI does not match what was rendered on the server.]
Warning: An error occurred during hydration. The server HTML was replaced with client content in <div>.
Error: Hydration failed because the initial UI does not match what was rendered on the server.
Error: There was an error while hydrating. Because the error happened outside of a Suspense boundary, the entire root will switch to client rendering.
```

These seem to be the correct warnings to fire in `createRoot`, so the
fix is to update the number of warnings we expect.
