Open dashboard in browser automatically when launching from CLI

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Is your feature request related to a problem? Please describe the problem.

I am always running `aspire run` in a separate terminal and then waiting for it to spin up and click the dashboard link. Then I continue coding in VS code.

### Describe the solution you'd like

I'd like to have a CLI option or an Aspire config setting that I can set so it automatically launches the dashboard in the browser. Maybe `aspire run --launch` or `aspire run --launch-dashboard` (or something else).
