**Is your proposal related to a problem? Please describe.**

Adding a .github folder with issue and pull request templates for uniformity.

**Describe the solution you'd like**

The .github folder contains one subfolder: ISSUE_TEMPLATE and PULL_REQUEST_TEMPLATE.md. Inside the ISSUE_TEMPLATE folder, there are two markdown files: bug_report.md and feature_request.md.

**Describe alternatives you've considered**

Referencing other popular hugging face repositories to study how they have it setup.

**Additional context**

I've observed the effectiveness of uniform templates in enhancing collaboration and communication in general.

PS:
In addition to this proposal, I've noticed that both Sanchit Gandhi and Yoach Lacombe have made significant contributions to repositories such as diarizers, parler-tts, and distil-whisper. Inspired by their contributions, I'm interested in extending similar enhancements to those repositories by adding the .github files with issue and pull request templates. Before proceeding, I would like to confirm if it would be acceptable for me to contribute in a similar manner to those projects.
