chore: update install engines

[jcesarmobile]

master version was bumped to 4.0.0-dev, so the package.json should have a new "5.0.0" entry or will fail to install once released.

Updated the "4.0.0" to require cordova-ios >=6.0.0-dev since the ios breaking changes will only work in that new version.

Also updated the engine in plugin.xml for also require cordova-ios >=6.0.0-dev.

Kept the cordova >=3.1.0 as nothing was changed to require a newer version, but maybe we should require at least 9?

cordovaDependencies is new to me, but changes make sense. 👍

Tests fail with:

  cordova-plugin-inappbrowser-tests.tests >>

    cordova.InAppBrowser

      ✗ inappbrowser.spec.1 should exist

        - Expected undefined to be defined.

Maybe the dependencies cannot be loaded because the -dev versions are not on NPM?

[jcesarmobile]

Yeah, since this requires cordova-ios 6, test won’t work until it’s released. But better have it here so we don’t forget.

[jcesarmobile]

Looks like I was wrong and cordova-ios 6 is not required for IAB to work, master is working fine on 5.1.1.
So changing the requirement to 4.0.0 as some 4.0.0 code checks were removed and older versions won't work, but should work on 4+.

[NiklasMerz]

Quick test was good, too.

I think minimum Cordova version should be increased as well, both here and in plugin.xml. I don't think we want to keep supporting old Cordova versions:)
