fix(schematron): Correct download URLs for XRechnung and PEPPOL validation files

- Fixed XRechnung URLs to use correct filenames (XRechnung-UBL-validation.sch)
- Removed non-existent PEPPOL-T10 and PEPPOL-T14 files
- Added PEPPOL-EN16931-CII validation file
- All 7 validation files now download successfully:
  - 3 EN16931 files (UBL, CII, EDIFACT)
  - 2 PEPPOL files (UBL, CII)
  - 2 XRechnung files (UBL, CII)
