Shorter syntax for `dart run https://pub.dev/<package>`

[sigurdm]

The new remote run feature requires writing the entire host name including the scheme.

It would be great if there was a shorter form for the case where the host is pub.dev.

Maybe:

> dart run /package

or

> dart run package@

For reference the current syntax is dart run https://pub.dev/package.

My initial thought was that most people will copy one-time-run commands from code blocks in readmes, so then the length doesn't matter that much. However, I'm not opposed to a shorthand for pub.dev 👍

Another option is: dart run pub/package
