Suggestion: Add category auto-generation support for publications in publications.py script in markdown_generator

[TAT-Hins]

Hi everyone,

First of all, I would like to show my respect to the whole development team and the community that I am able to have such a great project for my personal page.

I love the markdown_generator particularly since it helps me save a bunch of time creating and adjusting so many single markdown files in similar formats. However, I noticed that the publications.py script seems to lack support for the category attribute of the publications. I now have to add this to every single publication markdown files, which means I didn't save much time since I still have to open these files one by one every time.

I have not tried to use Jupyter Notebook and I didn't check the .ipynb files so I'm not sure if there are the same problems, but I really hope that this feature could be supported in the python script someday.

Anyway, academicpages is definitely a wonderful project. Salute to everybody here!

Best regards
