Add issues template for documentation issues

[suhanipaliwal]

I would like to add a issues template for documentation issues in this repository. I believe that having a standardised template will help streamline the contribution process, ensuring that all necessary information is included and making it easier for maintainers to review issues.

Could you please assign this issue to me under GSSOC'24.
