Breaking Change in GitHub actions/upload-artifact@v4

[misterjoshua]

In GitHub's actions/upload-artifact#598, they disabled the inclusion of dot files/hidden files by default without releasing a major version change.

As a result, the cdk.out uploaded by CDK Pipelines for GitHub Workflows now omit dot files. The missing dot files have begun breaking several of my pipelines that rely on DockerImageFunctions that reference dotfiles like .yarnrc.yml while building a container image asset because required files are missing from the staged assets.

We need the upload-artifact action input to include include-hidden-files: true so the hidden files we require are included.
