[lgleim]

Resolves #592

While the CONTRIBUTING guidelines already provide significant guidance on how to structure Bug reports & Feature requests, the large majority of current issue reports does not follow them.

To ensure more structured & time efficient project management, this PR introduces templates to encourage useful issues and pull requests.

This makes it easier for new users to contribute in a structured manner by guiding them in creating useful reports in alignment with the contribution guide, thus

saving reviewers time
improving the quality of issue reports and feature requests
direct questions to the community discussion page
ensure required PR preparation steps were honored

Thank you so much for the initial template!

Could you add CUDA version / nvidia-driver version for the BUG report environment section?
Also - CPU/CPU [e.g. A100, RTX 4090, M3pr, Intel I9-9900k, Ryzen 5900x] is this a typo for GPU?
