docs: Update version strings from Bookworm to Trixie

Changes all Debian version references:
- Title and heading (Bookworm → Trixie, fixed underline length)
- APT repository URLs (bookworm → trixie)
- Security repository (bookworm-security → trixie-security)
- Updates repository (bookworm-updates → trixie-updates)
- Debootstrap command (bookworm → trixie)
- GitHub issue URL
- Version-specific notes

All changes are mechanical string replacements. No functional changes
to the guide structure or instructions.
