[FeatureReq - Partner Center] Enable cross-browser V3 manifests

[lsmith77]

**Is your feature request related to a problem?

We encountered this warning:

The issue is that we want to be able to use the same manifest for Firefox, which has different requirements. So from our point of view the validation in the Microsoft Edge store is too strict. Note that the Chrome store doesn't do such strict validation either.

Firefox still uses "scripts" https://stackoverflow.com/questions/75043889/manifest-v3-background-scripts-service-worker-on-firefox/78088358#78088358

Hence we changed our manifest from

  "background": {
    "service_worker": "js/background.bundle.js",
    "type": "module"
  },

To

  "background": {
    "service_worker": "js/background.bundle.js",
    "scripts": ["js/background.bundle.js"],
    "type": "module"
  },

to still support Firefox after the v3 migration.

Describe the solution you'd like
Ignore scripts in background if service_worker is present and pointing to the first element in a single element array in scripts

Describe alternatives you've considered
Ignore scripts in background
