Fix 404 links and Automate Check using Lychee (#127)

* Fix 404 broken links and add automated link checker CI

1. Fixed dead links across the repository:
   - AdBypasser URLs migrating from github.io to the main github releases tab.
   - Codeberg discussions/issues pages that reported 404, pointing them strictly to their main repository URL.
   - GitHub discussions/issues tabs returning 404s, standardizing them to point correctly toward current Issues pages.
2. Added Lychee link checker GitHub Action to prevent link rot going forward.

* Fix syntax in GitHub Action for Lychee

* Add workflow permissions and exclude ghostbrowser.com from lychee checks to prevent timeout errors
