fix(@angular/cli): force temporary directory for non-registry specifiers

When resolving package manifests from file, git, or remote URLs, the CLI relies on installing the package into an isolated temporary directory to identify the package's name. This change forces the 'acquireTempPackage' method to use the 'temporary-directory' strategy for these lookups, ensuring that the package identification logic remains correct even when the package manager (like Bun) defaults to a 'project-root' strategy.
