Adding a pull request template to the repository as like issue template

[Gmin2]

Describe the bug

Currently, our repository lacks a pull request (PR) template, which can provide helpful guidance and ensure consistency when contributors submit PRs. To improve our PR process, we should add a PR template to the repository.

Expected behavior When creating pull request contributors will be ask to specify what issues it solves(issue number) and if they have run the lint while making the changes

Notes Would like to work on it
