👻 force npm9 during image build

Ever since the build container we use [1] updated to use
`npm@10`, the image builder github action has encountered
a number of problems. The first was solved with konveyor#1746.
The second more random problem has been with network
connections erroring out when installing dependencies.

To work around the network error, force the build to use `npm@9`.

Alternative solutions:
  - Add the force to `npm@9`` directly in the Dockerfile for use
    in all circumstances

  - Use the `:1-88` version of the build container instead of
    `:latest`

  - Find a way to use something like verdaccio to proxy/mirror
    the npmjs repo during the build so npmjs fetches can be
    pooled across the parallel image builds
