fix: update requirements + convention

[spartanz51]

Added "rich" dependency (version 13.5.3) to the requirements.txt file

Additionally, I renamed the reqs.txt file to requirements.txt, aimed at following the widely accepted convention in the Python community, to minimize inconsistencies across repositories, especially within the SD Nodes/models ecosystem, which is sorely lacking in standards :)

Hi,

Thanks for the suggestions but I will change most of this soonish.
There is a reason I'm not using "requirements.txt" as Comfy Manager detect and install the requirements.txt but because of some issues on windows (especially comfy portable) I need to bundle wheels (the ones referenced in reqs-win.txt) so I cannot only rely on pip markers, that's what I was doing before.
My idea is to remove these dependencies by default on windows and add a way to diagnose and install potential missing requirements later in the ui at /mtb

Rich and rich_argparse are only used in the scripts that aren't used by the nodes, but I could add instructions to pip install rich
