Incorrect Node22 warnings on load

[iliapolo]

Using the CDK cli with Node22 produces the following warning:

It happens as soon as the CDK cli is loaded, see: https://github.com/aws/aws-cdk/blob/main/packages/aws-cdk/lib/cli.ts#L2

However, this is actually inaccurate, because support for Node22 was added a while back, and it exists in our testing matrix as well. For example:

Looks like there's either a bug in how we determine tested versions, or we missed something when adding node 22 support.

False alarm. The warnings are due to an old version of CDK:
