[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

This is not specifically an Edge issue. Mozilla and Chrome don't seem to have agreed on the specific syntax, which as you pointed out, is different for both browsers. Edge is based on Chromium and will expect the Chrome syntax.

You will have to have 2 manifest.json file and build separate packages for Mozilla vs Chome/Edge.

No, they did, as of versions 121:
