fix: use latest global workflow and remove link checkers

[derberg]

This PR:

• uses latest replicator -> https://github.com/derberg/manage-files-in-multiple-repositories/releases/tag/v2
• in theory, because .github/workflows/link-check-cron.yml,.github/workflows/link-check-pr.yml are removed from repo and config, bot should remove these check from all the repositories in AsyncAPI org

Fixes https://github.com/asyncapi/.github/issues/199

---

if someone wants to have these workflows in repository, they should open a separate PR to add these files as separate configuration, that someone can opt-in only by using some specific repository topic name
