[DOCS] : Add issue template and PR template #26

[AshutoshDash1999]

Hi,
I want to add issue template and PR template for issues and PRs format respectively.

It will help in checking the issues as they will follow the same format.
Same for PR as well, contributors have to follow certain format, and help you focus on code review.

Please assign this to me under SSOC26.
