fix: broken documentation URLs in link checker

1. remote_mining.rs: dicle.subscan.io -> explorer.pezkuwichain.io
   - subscan doesn't have our testnet, use our explorer

2. ethereum-client + beacon primitives: consensus-specs/blob/dev -> blob/master
   - ethereum repo uses 'master' branch, not 'dev'
   - 5 URLs updated
