MT#55391 update package to be build with node 18

* debian/rules:
  - set explit NODE_PATH env to correctly locate
    system node pacakages that are installed by yarnpkg
    during the build stage
  - add NODE_OPTIONS=--openssl-legacy-provider
    as quasar v2 uses webpack v4 atm and this option is for
    backward-compatibility until webpack is upgraded to v5
* debian/control
  - add dependency on node (>= 18) to avoid this
    package to be run on older node versions for consistency
  - add dependency on python3 as otherwise the built-in
    'multiprocessing' module is not there (required by gyp build)
