Update PackageUpdateResource to receive bool to indicate if snupkg are enabled

[jgonz120]

Bug

Fixes: NuGet/Home#11871

Description

SymbolPackageUpdateResource is currently only being used in PackageUpdateResource to determine if snupkg are enabled for symbol sources. Since the push command allows users to specify a SymbolSource, there may not be a SymbolPackageUpdateResource available. This created a new function which takes in "allowSnupkg" as a parameter instead of trying to determine if it's available based on whether or not SymbolPackageUpdateResource is null.

Looks good, but we need tests.

I see you've crossed off the added tests part but there's no justification for missing tests.

https://github.com/NuGet/NuGet.Client/blob/dev/test/NuGet.Clients.FuncTests/NuGet.CommandLine.FuncTest/Commands/PushCommandTest.cs has some tests.

Ideally, we can consider adding these tests to dotnet nuget push instead.

The setup code should be very similar.

I had left some comments, but didn't click submit :D

lgtm but I'm not an expert on this area

PR Overview

This PR updates the PackageUpdateResource and associated push logic to accept an explicit boolean flag for enabling snupkg pushes, addressing the issue where SymbolPackageUpdateResource may not be available when using a SymbolSource.

• Introduces a new PushAsync method and overloads to control snupkg support explicitly.
• Adds new integration tests in PushCommandTest to validate push behaviors for packages and symbols under various configurations.
• Modifies the setup of mock servers to return the proper push endpoint and updates variable naming in the PushRunner.

• Consider using a proper URL concatenation method (e.g. using UriBuilder or ensuring a trailing slash) to guarantee the returned URI is well-formed.

return server.Uri + "push";

• The variable name 'symbeSourceUri' appears to contain a typo; consider renaming it to 'symbolSourceUri' for clarity.

var symbeSourceUri = symbolSource;
