Winget-cli: winget update

[AdilHindistan]

Description of the new feature/enhancement

winget install xyz seems to install an app even if that same version is already installed.
There must a distinction for a new install vs an update of an existing version to a newer one.

• winget update winget # updates winget to the latest version
• winget update app1, app2 # updates app1 and app2 to their latest versions in repo
• winget update python==3.8.1 # updates currently install python to version 3.8.1, if it exists in the repo
• winget update --all # updates all existing packages to their latest version
