Allow only runtime to be installed

[Frulfump]

Description:
Add an option that forwards to the corresponding install-script option.
The install script supports the --runtime option https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-install-script#options

Justification:
Runtime is smaller and when you only need the runtime it's better to not get excess capabilities.

Are you willing to submit a PR?

Not really

Hi @Frulfump 👋,
Thank you for the feature request. We will investigate it and get back to you as soon as we have some feedback.

@priyagupta108 Thank you. How long does that usually take I see some other recent issues left in this state for more than three months? I assume this would be easy to implement with GitHub Copilot.

I'm willing to submit a PR for this, if needed.

The only question would be the default value. The install script treats any runtime argument value which isn't dotnet, aspnetcore or windowsdesktop as "install SDK instead". Should the default non-runtime value be sdk, none or something else?

[Athari]

Oh, never mind. This issue is a dupe of:

• Add ability to install just the runtime, rather than the SDK #352

And there's already a pull request:

• Install runtime only #476

It's also merged into the akv-platform/setup-dotnet fork in this pull request:

• Add ability to install runtime only akv-platform/setup-dotnet#18

This doesn't allow passing all variants of runtime (only true/false), but can easily be improved.
