Can you:

1. Bump the NodeJS version in that VM to version 22
2. Pre-install the test runtimes with npx playwright install --with-deps
3. Ensure you have set the environment variable CI to true (this will help your environment behave more like the GH environments)

Also the new tests will need egress to play.hpccsystems.com.

If you want to skip the test and have the same behaviour as before, you can change npm run test to npm run lint.
