GSoC 2023 Project Idea 22.1 Update Brian documentation infrastructure (175h)

Hi @Chandraprakash-Darji. The general resources I mentioned for the other project are obviously the same here. Regarding this specific project, the most important thing to look at would be to see how our documentation is built (see e.g. the notes at the beginning here: Documentation — Brian 2 2.5.1 documentation). The documentation is built using sphinx and automatically updated/hosted via readthedocs.org. The examples and tutorials are provided as jupyter notebooks. Let us know if anything is unclear!
