Add warnings to various pages that pertain to either conda or NX, cfr. #122

• In source/access/nx_start_guide.rst, I propose an few lines like this:

If you would like to use NX and conda, follow these instructions for a clean setup:

• open your .bashrc, and find the relevant lines which modifies the $PATH and also initializes conda
• copy these lines and paste them into a new file called $VSC_HOME/conda.start
• clean your .bashrc from all those lines which modifies $PATH and initializes conda
• You can now safely login to NX. Next time you want to use conda, you have to execute source $VSC_HOME/conda.start in your command prompt or inside your PBS job script

• In https://github.com/hpcleuven/VscDocumentation/blob/feature/conda_bashrc/source/leuven/running_jupyter_notebooks.rst#prerequisite-nomachine the :ref: is not rendered, because of a typo

• In https://github.com/hpcleuven/VscDocumentation/blob/feature/conda_bashrc/source/software/python_package_management.rst#install-miniconda, we are misguiding the users with adding conda path to $PATH. Instead, we can advice them to have a secondary file like conda.start

• The same could also apply to https://github.com/hpcleuven/VscDocumentation/blob/feature/conda_bashrc/source/software/r_package_management.rst#installing-miniconda
