V4 broken for TS `nodenext` users

[trevor-scheer]

Lots of errors like this:

node_modules/@apollo/server/dist/esm/externalTypes/plugins.d.ts:6:344 - error TS2835: Relative import paths need explicit file extensions in EcmaScript imports when '--moduleResolution' is 'node16' or 'nodenext'. Did you mean './requestPipeline.js'?

Repro: https://codesandbox.io/s/musing-albattani-s8v12i

Looks like we just need extensions everywhere, not just runtime imports.

The same issue desperately needs to be fixed in @apollo/client: apollographql/apollo-client#9890 .
