Cdk-ssm-document

Removes dependency cdk-iam-floyd

Adds support for document attachments and versionName for SSM Distribution packages 22

Starting with this release, the package is (only) compatible with AWS CDK v2.

For CDK v1 use any previous version.

Also there won't be any support for .Net/NuGet going forward. (those packages have most probably never worked anyway)

Include `js-yaml` as bundled dependency. The package was not usable with anything other than node.
