fix(iOS): migrate from depracated websocket method in RCTCxxInspector…

…WebSocketAdapter (#47197)

Summary:
Saw this while going through the remaining warnings of the project. I double checked, and i can't find any other usages left behind, so this is probably the last one

## Changelog:

[INTERNAL] [FIXED] - Switch to using the new sendString method for Websocket

Pull Request resolved: #47197

Test Plan:
yarn test:

Running the tests in Xcode with `CMD+U` or the objc-test: I could not get it to pass in either the old code or the modified code. I know the test documentation said it needs a WebSocket, but it was a bit too vague , and even turning metro on did not help, so i have no idea how to test it. If anyone can guide me on that one, please let me know
