Fix codemods execution on node 16

[dac09]

• [x] Run jscodeshift programatically https://github.com/redwoodjs/redwood/pull/3754
• [x] Check that npx can execute it correctly on:
  • [x] Node 14
  • [x] Node 16
• [x] Ensure codemods are finding files correctly
• [x] Ensure that codemods can be debugged from source (using RWJS_CWD=xxx node "dist/codemods.js")

I've checked all of the cases using the update-scenarios codemod, but it looks like it doesn't run any changes when we try to invoke it from dist/codemods, for debugging.

I think it must be to do with the fact that we need to pass CWD when we execute it programatically.
