Bitnami images to be moved to legacy repository

Created by: piotrgrubicki

As can be read in https://github.com/bitnami/charts/issues/35164, the bitnami repository is changing its policy. Starting on Aug 28th, Geti installation will fail because we are using these images extensively. Short term solution: switch our images to the legacy repository. Long term solution (another issue): switch to other maintained images.
