Remove unused scope Nuget::Package.without_nuget_temporary_name

Summary

Removes the unused scope Packages::Nuget::Package.without_nuget_temporary_name from app/models/packages/nuget/package.rb.

Related to #542966 (closed)

Verification

This scope was verified as unused by:

• keela --type scopes flagged it as unused
• Grep search found no callers in app/, lib/, ee/
• Not used in scope chaining
• Not used in merge() calls
• Not used as default_scope, association scope, or via symbol/metaprogramming

The scope's referenced constant Packages::Nuget::TEMPORARY_PACKAGE_NAME remains in use elsewhere (for example lib/api/nuget_project_packages.rb), so it was left in place.

Cascade Removals

None - this was a standalone removal.
