When a vcc package is downgraded from a version specifying to one specifying , the following error is thrown and the downgrade is blocked:

"Incompatible Package - You are trying to downgrade x to a version that no longer supports Unity 2022.3.22f1 used by your project, this will cause issues and is not supported."

This is incorrect, because the unity field specifies a minimum supported version, not a range or a maximum.
