Reference: prettier/prettier#8805

I had a major brainfart when implementing #2305 and didn't think about the fact that changes should be backwards compatible.

When handling the null type change introduced by 4.0, I deleted the old branches instead of gating them behind a version check. This PR just gates the old logic for < 4.0.

We don't have automated testing against old TS versions yet (#1752) so I tested this by hand by doing the following:

  • yarn build to build against 4.0.0-beta.
  • change the resolved ts version to 3.9.7
  • yarn install --ignore-scripts (the automatic rebuild after the install would fail due to incorrect types)
  • cd packages/typescript-estree && yarn test ast-fixtures
  • inspected the test output to ensure the only failures were due to fixtures for 4.0 features.
