Use Node 22 (current LTS) for development

• Drop Node 18 for testing builds.
• Add Node 22.x to dev engines.

I would update package.json in such way, that I would remove engines section and introduce devEngines:

  "devEngines": {
    "node": "20.x || 22.x"
  },

This is how React does it. RUI does not required any specific version to run, only dev environment does.

What do you think @adamkudrna @mbohal ?

I agree with using devEngines. However the code example provided by @bedrich-schindler is wrong.

See: https://docs.npmjs.com/cli/v10/configuring-npm/package-json#devengines for usage. I wonder if we should fail or warn on error. I think I would prefer to fail…

@mbohal good point. It is weird that library like React have it wrong, but you are right unless there is some undocumented approach.
