fix(ssr): remove package json from dist-hydrate-script

[johnjenkins]

The auto-generated package.json that Stencil inserted within the hydrate dir is too prescriptive and overrides user's main pacakage.json settings.

What is the current behavior?

The auto-generated package.json looks something like:

{
  "name": "your-project/hydrate",
  "description": "YourProject component hydration app.",
  "main": "index.js",
  "types": "index.d.ts",
  "exports": {
    ".": {
      "require": "./index.js",
      "import": "./index.mjs"
    }
  }
}

Which can overrule settings within developers' main package.json

What is the new behavior?

The contents of package.json has been changed to {"type":"commonjs"}; the bear minimum to not cause a breaking change
