fix(scancode): Ensure to find license texts in the Docker image

Dump the ScanCode license texts to directory /opt/scancode-license-data when creating the ORT docker container. Use this directory as fallback option if the ScanCode license texts cannot be located by the existing heuristic algorithm. Fixes oss-review-toolkit#8147.
