Add dnsprovejs@0.5.1 patch for RFC-compliant DoH queries

This patch fixes DNS-over-HTTPS queries to properly comply with RFC 8484 and RFC 4648 §5:
- Adds base64ToBase64Url function to convert standard base64 to base64url encoding
- Updates dohQuery to use base64url encoding for DNS parameters
- Sets correct Accept: application/dns-message header

Ported from ensjs-v3 repository.
