Deprecate but not delete, because it's in several examples.

@ascorbic, just waiting to hear back from the Remix team about how we're handling this, i.e. not modifying the Remix compiler code. See remix-run/remix#3104 (comment) and https://discord.com/channels/770287896669978684/928816717172445204/972164970617917520

We're no longer deprecating this. This will still be the repo for the Netlify Edge Remix template.
