fix(cloudformation-diff): @aws-sdk/client-cloudformation should be a peer dependency

[mrgrain]

The function signature of fullDiff depends on the DescribeChangeSetOutput type from @aws-sdk/client-cloudformation. Therefore this package should be a peer dependency, not a dev dependency.

Updates the dependency type, and adds the minimal version as a devDep to ensure we stay compatible. I needed to add 0BSD into the license checker since one of the transitive dependencies use it. It is an approved license.
