suggestion: Using templates for better issues and PRs

[hanpham32]

I think this is a good guideline to implement as we start to grow our open-source dev community here:

https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/syntax-for-issue-forms

Happy to contribute on this too :^)

Makes sense, should keep it simple though.
