[release/13.0] Filter to highest package version per channel in aspire add command

Backport of #12553 to release/13.0

Customer Impact

This PR addresses an issue in the aspire add command where we show two versions of a package when a channel is chosen when only one should be shown. The underlying reason is that a channel is often comprised of multiple feeds (e.g. the daily feed references dotnet9 and nuget.org) and in the case of the Docker integration there is a pre-release package in both.

This update effectively filters the list so we only show the highest version across package sources.

Low risk and contained to the specific command. Marking as approved, but I also think that if we think this may impact other things we can also hold off for 13.1

Agree

[joperezr]

@mitchdenny any final thoughts here? if we feel good about low risk of potential side effects I can go ahead and merge this.

[joperezr]

Removing approval for now since at this point we should just wait for 13.0.1

[joperezr]

@mitchdenny do we still want this one for 13.0.1?

[mitchdenny]

Yep
