Upgrade to React Native 0.76 and Expo 52

[smaye81]

Fixes #2134

React Native 0.76 / Expo 52 have added full support for streaming. This updates our example to leverage this new functionality and remove notices/warnings that streaming is not yet supported.

$ npx expo-doctor                                                                                                                                                                        Enabled experimental React Native Directory checks. Unset the EXPO_DOCTOR_ENABLE_DIRECTORY_CHECK environment variable to disable this check.

Have been waiting years for this 🎉

Not sure it's worth checking for this issue #2134 (comment). It has already been filed with a repro in expo/expo#33553, and it looks like a fix is underway. May be worth calling it out in a comment here, maybe the fix doesn't land for a while.

Yep, just wanted you to see how I was testing it. I was going to remove it when ready for review. Will add a link to the code here instead.

We're actually using the connect transport. Would be great to smoke test both with JSON and binary.

We also need to update README.md.

Tested with binary format also and can confirm all 3 areas work (web, simulator, expo go).

Updated README and also created connectrpc/connectrpc.com#244 for the docs.
