Doc: how to enable notifications

Summary of the new feature/enhancement

I disabled notifications long ago and forgot how I did it. Googling led me at first to group policy - not relevant.

The answer in Windows 10 is: Settings > Notifications & actions > Get notifications from apps and other senders

Proposed technical implementation details (optional)

Add short section in readme on how to find the setting in the Settings UI.

Once one notification has been shown, powershell appears in the list of apps that can be disabled individually.

Not doing

Configuring the setting in code on behalf of the user. I have in the past found it a PITA to manage user OS settings in code; apart from finding the relevant levers to pull, you have security boundaries. This is a one-off action for the user.

I would be pleased to PR the doc addition if maintainers think this should be done.

This actually helped me out. Wondering why BT stopped working and couldn't figure it out. Enabled Notifications and boom.
