[Bug]: Cannot add Fedora servers. Docker installation fails

[ahmetveburak]

Error Message and Logs

Thanks for this awesome service!

Findings

Coolify can be successfully installed to Fedora as localhost installation, but managed servers cannot be added.

As far as I can find, Adding a server and Revalidate Server, Validate Server & Install Docker Engine buttons trigger the Docker Installation from InstallDocker.php. This script forces to install the minimum version of Docker based on the constants.php.

This causes the install-docker script to fail since dnf returns only the latest versions.

Is there a specific reason for forcing Docker installation to an old version?
