fix: Ensure container runnable in deployment (#1) * Make /.run executable - Use '24.2.26' tag over 'main' for sslhep/analysis-dask-base base image. - Source the environment before performing tasks involving jupyter. * Add setup of AnalysisBase environment * COPY private_jupyter_notebook_config.py to jupyter config dir - c.f. https://docs.jupyter.org/en/latest/use/jupyter-directories.html#configuration-files * Set jupyter shell to bash to harmonize with AnalysisBase - The default without this is /bin/sh which is not as perferable. * Force a login shell for Jupyter to pickup ~/.bash_profile - This allows for setting up the AnlaysisBase environment by default. * Add Makefile for local debugging
