Display version number in settings

[SankethBK]

Settings page widget can be found at lib/core/pages/settings_page.dart. We need to show app's version number as defined in pubspec.yaml.

Create a new widget AppVersion in lib/core/widgets and display the app's version like this (Since this widget is not related to any particular feature).

You can either use package_info package from pub.dev or directly retrieve it from pubspec.yaml
