Create project-management.md with meeting details

PR for steps to create recurring meetings in discord

Please create a file project_management.md and add a section related to setting up Meetings and these details there. This helps in adding other sections of faqs related to project management in one place. Also, instead of giving outlook alone as an example, add how to do it from let's say google calendar as well.
