Plans to update docker image?

Success! Applying the following change to context/Dockerfile:

14c14,16
-     cert-sync /etc/ssl/certs/ca-certificates.crt
---
+     cert-sync /etc/ssl/certs/ca-certificates.crt && \
+     rm /usr/share/ca-certificates/mozilla/DST_Root_CA_X3.crt && \
+     update-ca-certificates

has backblaze connecting successfully in TrueNAS SCALE (and presumably elsewhere). That was the only change needed as well.

Edit: Note I did test a build of the Docker container without any modifications to verify the behavior before implementing the above fix.
