Project name change to `Schedulify` and add contribution docs.

[IAmRiteshKoushik]

Description

The existing repository name is too long and not very catchy. A name change would be a small upgrade for the project.

Also, was thinking about adding the following to standardize things in this repository :

[ ] Add - CONTRIBUTION.md [ ] Add - PULL_REQUEST_TEMPLATE.md [ ] Add - ISSUES_TEMPLATE.md
