Hi @AdamRaven and thaks for your contribution. Your PR brings in assets and configurations that are not affiliated with the EDC and thus should be hosted on a downstream project within your own GitHub-Org. Please have a look at https://github.com/eclipse-edc/.github/blob/main/contributing/adoption.md for further information. So please open an adaption request rather than a PR.
