[RFC] feat!: remove platform pinning

[erisu]

Platforms affected

none

Motivation and Context

• Stop managing the platform pinning.
• Always allow the use of the latest release version without requiring an update of the lib or cli.

Description

• Remove platform version pinning data.
• Remove logic for displaying the pinning version.
• Always fetch latest version when not supplied or already installed.

Previous concerns which shouldnt not be an issue anymore: Platforms relied on the common object which was passed to platform. Platforms should now be recreating the common object using its own installed common package.

E.g.

• cordova-android
• cordova-ios
• cordova-electron

Testing

• not fully tested... in progress
