include partial+full guide for custom pacakges

[ShaivanBhagat]

includes:

• partial (smaller) manual explaining custom packages and some quick info.
• a longer detailed manual with more detailed how to use, where envs are stored, how to work with jupyter kernels, and install additional packages

I have not linked this to VRE Lab workspace manual (yet). If this looks good, then I will include the partial in the Vre lab manual

Hi @ShaivanBhagat, Thanks so much for this contribution! I think it is very useful and complete, however also a bit on the long side. For the partial I provided a suggestion on how to shorten it. For the full manual I wasn't sure yet on what to remove. If you have ideas to shorten it, great! however, we could also keep it long for now and reduce later.

Since @dometto is author of this component, could you go over this and see if I missed some things in my review?

This looks great! Suggestions for shortening:

• "Using Environments in Jupyter Notebooks" <-- could potentially be moved to a separate manual? Not sure!
• The alternatives for python/conda in the various sections could be put in collapsible elements, so the manual doesn't appear as long for the enduser. This would also allow easily adding Julia at a later point.

Agree we can also merge as is and shorten later.

Dawa's suggestions make sense and will help shorten it. I will also see where can i shorten it without taking away much of the content. I can shorten the partials file to a good extent as well.

Hi @dometto @jelletreep, I have shortened the partial to some extent. For the full manual, i have used tabsets for conda/python-uv environments, and tried to shorten it as well. Let me know if it needs to be shortened further
