Generate .md files messages from badging bot repo instead of events-diversity-and-inclusion repo directory

[ayushtamra]

Description:

The badging bot messages/responses, for example: Welcome messages, Checklists, etc., are currently generated from the event-diversity-and-inclusion repository. These messages are stored in the .github directory in the form of .md files of the event-diversity-and-inclusion repository and are accessed through the GitHub API.

For proper management, debugging, and contribution follow-up, this issue will move the files to this repo.

Solution:

Migrating the .github folder to the badging bot repository/directory
