[Request]: Update Package.swift in all plugins to support updated format for SPM support

[vbuberen]

Plugin

Applies to all plugins

Use case

Since initial introduction of Swift Package Manager support more than a year ago (#3152) there were changes that require additional changes in the Package.swift file of all packages. Otherwise, there are the followign errors during iOS/MacOS build:

ERROR: Plugin package_info_plus has a Package.swift for ios but is missing a dependency on FlutterFramework. Add the following to your Package.swift dependencies:
    .package(name: "FlutterFramework", path: "../FlutterFramework")
And add FlutterFramework as a target dependency:
    .product(name: "FlutterFramework", package: "FlutterFramework")
See https://docs.flutter.dev/packages-and-plugins/swift-package-manager/for-plugin-authors for more information.

Proposal

Add missing lines to all plugins to get rid of errors during build with Flutter 3.44.x which uses SPM by default.
