Update cpy to v9 and use ESM-compatible import

[krissrex]

cpy changed from commonjs to esm in v9.
It also had a breaking change regarding parent option.

[krissrex]

The snapshots that changed path are likely affected by the breaking change in cpy.
An option might be needed, to not affect the snapshots

Fixed and force-pushed

codebuild aws/codebuild/standard:5.0 uses node12 and 14: https://github.com/aws/aws-codebuild-docker-images/blob/48b53e25cf36dcb1e0b124bc7bebfb342d161b91/ubuntu/standard/5.0/Dockerfile#L219-L229

while codebuild v 6.0 uses node16: https://github.com/aws/aws-codebuild-docker-images/blob/48b53e25cf36dcb1e0b124bc7bebfb342d161b91/ubuntu/standard/6.0/Dockerfile#L182

We use the default setting for codepipelines (CDK Pipelines), which is 5.0

liflig-cdk/src/cdk-pipelines/liflig-cdk-pipeline.ts

Lines 183 to 186 in fe5809e

	this.cdkPipeline = new pipelines.CodePipeline(this, "CdkPipeline", {
	synth,
	codePipeline: this.codePipeline,
	})

The 6_0 is not present as a default in CDK yet, but you can specify images using a name.

The code should still run in node12. But changing to codebuild 6.0 removes doubt
