Multiple issues were identified in FBC repository scripts that needed improvement for better maintainability, error handling, and code review readability.

  What needs to be implemented:
  1. Fix generate-catalog-template.sh to always remove 'replaces' field from first entry regardless of entry count
  2. Add proper error handling in generate-catalog-template.sh when skopeo inspect fails
  3. Improve catalog-template.yaml organization by adding sorting in add-bundle.sh
  4. Sort relatedImages in bundle files for consistency in render-catalog.sh

  Acceptance criteria:
  - First entry in every channel has no 'replaces' field regardless of total entry count
  - Script exits gracefully with helpful message when skopeo inspect fails
  - Catalog entries are organized consistently for better code review readability
  - Bundle files have sorted relatedImages for consistency
