Remove start.sh script from Container Scanning

Summary

Remove the container-scanner/start.sh script from the Container Scanning tool which was added in gitlab-org/security-products/analyzers/klar!1 (merged). This script is no longer needed now that Remove Container Scanning kubernetes workaround has been completed.

This was originally supposed to have been implemented as part of #33827 (closed), but it was not possible to remove the script at the time because it was blocked by #207451 (closed)

Improvements

Removes unnecessary code

Risks

This is a breaking change for older installations of GitLab which predate the changes made as part of %12.9 in !21188 (diffs).
