Summary

🛠️🚀📝

This pull request enhances the cloud workflow for sealos by updating the image building and pushing logic, fixing the TLS certificate generation, and improving the documentation. It also removes an unused file from the frontend module.

Sing, O Muse, of the valiant deeds of the sealos team
Who, with skill and wisdom, forged the cloud workflow supreme
They tweaked the init.sh script to make the certificate secure
And silenced the noisy openssl command with a redirect obscure
