Update AU1 to newer/newest package versions

Several packages in the default aurelia repo and related repos have low to critical vulnerabilities. It would be great if this can be updated once in a while.

Until AU2 and at least until EOL for AU1, regular maintenance for Au1 too is much appreciated!

Start by inspecting dependency manifests in the default Aurelia 1 repository and the related repositories mentioned in the issue, then review their current vulnerability reports. Done means the affected packages are updated to maintained versions and the low-to-critical vulnerabilities are addressed across the AU1 repositories.
