Deprecate NetworkingModule.sendRequestInternal (#54101)

Summary:
Pull Request resolved: #54101

Changelog:
[Android][Deprecated] Mark `NetworkingModule.sendRequestInternal` as deprecated

The `NetworkingModule.sendRequestInternal` method is an implementation detail of the `sendRequest` method and does not need to be public. In this diff, we mark it as deprecated ahead of removing it from the public API in a future release of React Native.
