[DOC] Add a known / common issues page

[jeertmans]

Currently, solution to common problems are hard to find and that creates duplicate issues.

It would be great to create a page with:

• Windows quality issue (and move this out of the README);
• manim-slides command not found;
• Using two different versions of Manim Slides (causing, e.g., a mismatch in configuration files);
• PyQT/QT* issue on Windows;
• PowerPoint issue with too many slides;
• Python3.12 issues;
• ...?
