The package version should be the target one
https://dnf.readthedocs.io/en/latest/command_ref.html#downgrade-command-label

"Downgrades the specified packages to the highest installable package of all known lower versions if possible. When version is given and is lower than version of installed package then it downgrades to target version. "

dnf downgrade ansible-core

should be the correct command
