Approach 02: Codeheat Template

The previous approach was not favourable as it is complex for the users.

## User flow:

1. User clicks "Add Contest" in the admin menu
2. Enters just the contest title
3. Clicks "Create Contest"
4. WordPress creates a new page with all the content from the template
1. This page is accessible in the pages of admin section and can be editable.
6. User clicks "Edit it here" and can modify the content using the familiar WordPress block editor

## Features to be added:

- [x] User can have the option to select among [multiple templates](https://github.com/fossasia/codeheat.org/issues/373#issuecomment-3271720159)
- [x] [Start and end date with dynamic fields](https://github.com/fossasia/codeheat.org/issues/373#issuecomment-3271720159)
- [x] [Redirect directly to editor](https://github.com/fossasia/codeheat.org/issues/373#issuecomment-3271720159) after creation
- [x] [improve security and prevent Cross-Site Request Forgery (CSRF)](https://github.com/fossasia/codeheat.org/issues/373#issuecomment-3271720159)
- [ ] #375
- [ ] Help menu can be added for tutorials (documentation/Video) for creating a contest
