Image update to clear new CVE. Please merge to dev then master

We have updated our image and re-built it on a dev branch. Scans clean now (new Jetty vuln needed resolution with a library dependency update, now done). 0 un-herited vulnerabilities! Please merge to development so we can get an official scan. (and to master if you're so inclined when it passes!) @kwami.delali @thomas.shepherd @andymaks
