feat: add Deskew PDF and Font to Outline tools with improved issue templates

New Features:
- Add Deskew PDF tool for straightening scanned/skewed PDF pages
- Add Font to Outline tool for converting text to vector paths
- Add translations for new tools in all supported locales (de, en, id, it, tr, vi, zh)

Improvements:
- Migrate GitHub issue templates from markdown to YAML forms
  - Separate templates for bug reports, feature requests, and questions
  - Add config.yml for issue template chooser
- Update sitemap.xml with new tool pages
- Update ghostscript loader and helper utilities
