[BUG] - conda-store image needs a release target and dev target in the Dockerfile

[dcmcand]

Describe the bug

Split from #599

conda-store, which does an editable install:

conda-store/conda-store/Dockerfile

Lines 22 to 23 in 64552a2
RUN cd /opt/conda-store && \
pip install -e .

❗️this is also the file used during releases which should not be the case

Expected behavior

To fix this, refactor conda-store/Dockerfile to have 2 different build targets.

1. The dev target should install dependencies in editable mode as the the current file does
2. The release target should not install dependencies in editable mode
3. The .github/workflows/build_docker_image.yaml workflow should be changed to use the release target
