Pull request template for ensuring consistent PR formatting

[TimOsahenru]

We need to add a Pull Request (PR) template to our repository to ensure that all contributors follow a consistent structure when submitting pull requests. This will help streamline the review process and ensure that all necessary information is included in each PR.

The template should include sections for describing changes, URL link to related issue, type of change, testing methods, and a checklist for the contributor(feel free to include any needed info)

Implementation details

• Create a new file named PULL_REQUEST_TEMPLATE.md in the .github/ directory.
• Add content to PULL_REQUEST_TEMPLATE.md

A PR came in for this already @JohananOppongAmoateng - Sorry about that.

They were cleared to work on it from our Office Hours held in the discord.

I will mention to them that they should use the standard procedure of claiming a task before getting the work done.
