CLI: Enhance image and container inspection behavior

[AmelBawa-msft]

Summary of the Pull Request

• Graceful not-found handling for inspect commands, container inspect and image inspect now
  catch not-found errors and print a friendly localized message to stderr instead of throwing an
  unhandled exception.
• Partial results on multi-inspect. When inspecting multiple items, found items are still returned in JSON output; missing items log an error and set exit code 1.
• New MessageWslcImageNotFound localization string added to Resources.resw.
• New E2E test suite for container inspect (help, missing arg, not-found, single, multi, mixed found/not-found).
• Updated image inspect not-found test to expect the new friendly error + empty JSON array output.

Pull request overview

This PR updates WSLC’s image inspect and container inspect CLI behavior to be more consistent with other “inspect” commands by returning JSON output (including partial results) even when some requested objects are missing, while emitting localized “not found” errors and a non-zero exit code.

Changes:

• Update image inspect to handle missing images by emitting a localized error, returning []/partial JSON on stdout, and setting exit code to 1 rather than failing the whole command.
• Add end-to-end test coverage for container inspect, including success, not-found, multi-inspect, and mixed found/not-found scenarios.
• Add a new localized string for the image-not-found error message.
