Add note to pins

[Trenly]

Description of the new feature / enhancement

As a user, I may not always remember why I have a package pinned. It would be nice if a note could be added when creating the pin and if the note could be shown when listing the pins

winget pin add NodeJs.NodeJs -v 17.* --note 'ProjectA requires version 17'
winget pin add Discord.Discord --note 'Squirrel installers go nuts with winget'
winget pin add PackageABC --blocking --note 'Upgrading wipes config - be sure to export config before update'
