Documentation: Submission Guidelines for Applicants

[bistaastha]

Currently, submission guidelines for Events and Projects are listed at:
https://github.com/Nebrethar/Docs-Diversity-Inclusion-Badging

Those can either be added to the README of this repository or as separate files here. Another approach would be to put these guidelines on respective Event and Project repos.

@badging/maintainers Where would these fit better?

[Nebrethar]

I believe that any information regarding exclusively Event or Project requirements can be most easily found in their own respective repositories.

TL;DR I recommend Event and Project requirements in Event and Project repos
