@subhojit777, many of the hosts you are adding are already present in the known_hosts file. Why add them again?

All possible hosts are found with this script but it fails keyscan for certain hosts. If -t rsa is working, maybe we should add that to the script and see if it works for all the hosts. If it does, we don't need to manually run it during build.

@hussainweb The workflow is working with the latest main. Can you please create a release, and let me know. I would like to point the action to a fixed release, rather than the latest commit.
Since the required domains are already added now in known_hosts, so there is no need of this pull request.
