Add welcome screen informing the user about GOA integration
The GNOME online accounts integration is planned to be removed with GNOME 46 (gnome-initial-setup#202 (closed)). Therefore the user should be informed in all apps using the online account integration that online accounts need to be setup in GNOME settings.
Let‘s add a welcome dialog that is shown on first start of calendar. It should tell the user that calendar supports online accounts and link to the dialog in GNOME settings. If the user already had some online account setup in settings the dialog could still tell the user which providers are already available in calendar and that additional online accounts can be setup in settings.
