feat(react-router): only render dev warnings in dev

[ThomasTheTitan]

I noticed that the 💿 Hey developer 👋 warning for missing hydrate fallback was rendering on my prod application in addition to my dev environment. From looking in the code base, it looks like there is some precedent for only rendering these in dev. This PR tries to consolidate that and also updates the message to point at RR docs instead of Remix docs.

There are a ton of ways to do this, so curious for feedback! For example, I wasn't quite sure where the best place to consolidate ENABLE_DEV_WARNINGS was.
