Update with-relay-modern and with-relay-modern-server-express (#6182)

Update examples with-relay-modern and with-relay-modern-server-express to react-relay 2.0.0

- react-relay has started to use new Context API instead of Legacy Context API
- add `parseInt` because graphql 14.0.0 introduced stricter scalar value coercion

Closes #6157
