🌱 [backport release-0.4] Add and allow test image builds for more cha…

…nges (#1926) (#1927)

Changes:
  - If any of the `package.json` files change, test the image builds. We
    want to make sure that changes to the `engine` or `script` blocks
    receive a full image build testing.

  - Update the npm version check to `>=9.5.0`. This will allow the test
    image build CI to check new builder images that also have npm major
    version updates.
