Attempt to debug hydration error

[jplhomer]

To reproduce errors:

yarn
yarn dev

# In a separate tab:
cd templates/template-hydrogen-hello-world && yarn dev

See #920

Notes:

• From what I've deduced, we seem to be able to reproduce a hydration error when a new client component reference is streamed in as the result of a suspended component, meaning the client has to re-suspend in order to dynamically fetch the JS module.
• I can "fix" the issue by wrapping the host of the new client component in an additional Suspense boundary, but this does not seem like the expected behavior.
• Updated to the React build from this PR: Do not replay erroring beginWork with invokeGuardedCallback when suspended or previously errored facebook/react#24480
• Also updated to a more recent version of Flight for our Vite plugin, but that doesn't seem to have an impact

Note that the inclusion of any client component which renders HTML, and which needs to load via dynamic import causing suspension, will result in a hydration mismatch error. If you comment out this Button component, other client components are still dynamically imported but do not result in a hydration mismatch.
