Fix entrypoint path in Dockerfile for src directory change

Missed a path change in the docker file. If I pull the latest and over ride the entrypoint it runs just fine:

$ docker pull ghcr.io/asfhyp3/hyp3-autorift:test
$ docker run ghcr.io/asfhyp3/hyp3-autorift:test --help
docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/hyp3-autorift/hyp3_autorift/etc/entrypoint.sh": stat /hyp3-autorift/hyp3_autorift/etc/entrypoint.sh: no such file or directory: unknown.

$  docker run --entrypoint /hyp3-autorift/src/hyp3_autorift/etc/entrypoint.sh ghcr.io/asfhyp3/hyp3-autorift:test --help
