Consider showing the current Aspire version in the dashboard

We could put it in a footer or in the settings dialog. Would be nice to be able to immediately identify what version is running.

I could see maybe having the version of Aspire.Dashboard (or similar) in the footer, which would give an at-a-glance general idea of what version people had, and then something in settings or otherwise with a lot more details (Aspire.Hosting version, sdk version, workload version, etc) especially since it's possible for them to diverge from a common baseline in various ways.

Wonder if it that last part could (eventually) be driven by a dotnet Aspire tool command.
