Create curl/bash and curl/pwsh scripts to easily acquire the Aspire-CLI executable for all platforms (Windows, Linux, MacOS)

Part of the CLI bundling tasks

The instructions should be very simple and the url should be easy to find, for instance: curl https://get.aspire.dev/latest | bash

How fancy do we want to make these scripts? I assume we will want:

• install the latest version
• install version X.Y.Z

But do we also want the concept of a "channel" (or think docker image tag):

• install the latest "v9"
  • yesterday "v9" might have given 9.3.1. today it gives 9.4.0.
• install the latest "v9.3"
  • yesterday "v9" might have given 9.3.1. today it gives 9.3.2.

Maybe we don't need full blown channels. But just wildcard versions: 9.*.* or 9.3.*

• curl https://get.aspire.dev/latest | bash /dev/stdin -Version 9
• curl https://get.aspire.dev/latest | bash /dev/stdin -Version 9.3
• curl https://get.aspire.dev/latest | bash /dev/stdin -Version 9.3.2

Also, do we need a --prerelease flag?

The P0 experience is to get latest working. From there, first stretch is to get X.Y.Z, and then supporting channels as you suggest would be the next phase. Currently I'm only counting latest to be the main deliverable for 9.4
