Cleanup noisy test output (#20015)

This PR cleans up the noisy test output where some `console.warn`
messages were leaking into the test output.

This also uses the `src/` files instead of the `dist/` files of
`@tailwindcss/node` to get rid of a source map related warning in tests.
It also means that we don't have to rebuild `@tailwindcss/node` when we
make changes.

## Test plan

1. Existing tests pass
2. Output is clean when running tests (`vitest run --reporter=minimal`)
