Relay Environment type issues when upgrading to react-relay 16.x

tl;dr we are seeing `Type 'RelayModernEnvironment' is not assignable to type 'Environment'.` after upgrading even with code right from docs.

We are attempting to upgrade from react-relay 14.x to 16.0.0. Our dependencies are now: react-relay 16.0.0, relay-runtime 16.0.0, @types/react-relay 16.0.0, @types/relay-runtime 14.1.15, babel-plugin-relay 16.0.0, relay-compiler 16.0.0.

We are seeing `Type 'RelayModernEnvironment' is not assignable to type 'Environment'.` with all our uses of environment.

I simplified the case by copying this set up right from the [docs for RelayEnvironmentProvider here](https://relay.dev/docs/api-reference/relay-environment-provider/):

Because this is just passing in the environment directly from `new Environment(..)` as the docs show I'm not sure what the issue is with the RelayModernEnvironment vs Environment
