Remove config files after a 'npm uninstall'

[Jwaegebaert]

When a user uninstalls our package, config files like .cli-m365-all-connections.json are not automatically removed. These leftover files should be cleaned up to maintain a tidy environment and prevent potential issues. We need to explore a solution that ensures these files are properly deleted during the uninstallation process, avoiding unnecessary data persistence.

Just had a quick look at the npm docs and it doesn't seem like we'll have an easy way to hook onto uninstall events:

Due to the lack of necessary context, uninstall lifecycle scripts are not implemented and will not function.

Good find. We might need to consider a separate command that does the cleanup such as m365 uninstall. After cleaning up, it would show a message to run npm uninstall.

What if we just create some uninstallation guidance around that? A separate command to do that seems a bit if an overkill for me.
