Add JSON Schema for package configuration

[mmurto]

Add a JSON Schema for package configuration for IDE validation.

Can be tested with VSCode by adding the following in .vscode/settings.json of a workspace containing package configurations and copying the schema to schemas/package-configuration-schema.json of the workspace:

{
  "yaml.schemas": {
    "./schemas/package-configuration-schema.json": [
      "source-artifact.yml",
      "vcs.yml"
    ]
  },
}

Note: this should be correct according to the JSON Schema spec, but vscode-yaml plugin currently does not correctly handle it. The plugin does not produce error if both vcs and source_artifact_url are provided.

LGTM, but maybe @MarcelBochtler can chime in as he's got the most experience here.

Also, can we submit this to a schema registry, too?

That would be great!

I tested it and it works great :)

I also hoped that it would be possible to use this package-configuration schema and somehow include it as a reference in the repository-configuration-schema.json.
But as I didn't find a way to do that some months ago, I'd be okay, to duplicate the data.

I haven't tried it myself, but according to this, it should be possible to refer to schema from inside of another.
