fix discord invite link

[QWIILXEY]

Summary

the link to the discord server (https://ulnk.it/blp-discord) is dead nor does the main domain (ulnk.it) ping.

Checklist

• I have verified that I have not modified the following files:
  - inside the adguard folder
  - inside the alt-version folder
  - inside the dnsmasq-version folder
  - everything.txt

Because those files will be automatically updated using GitHub Actions!
