Add GitHub Issue Templates

[ajitzero]

Many dummy issues are being created, possibly by people unfamiliar with the GitHub interface. Using GitHub Issue Templates should help reduce these unintentional issues raised.

Reference on how to create issue templates: https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/configuring-issue-templates-for-your-repository

I suggest adding the following custom templates:

• New: Submit a new resource.
• Bug: Fix a broken link or typo.
• Other: Suggest general improvements.

Problematic issues so far:

• System Design  #2 .. #3 System Design Playlist #17 System design  #19 Kuch bhi #21 Sys_design #22 System design #23 GitHub #24 astro-fe #34
• Awesome System Design Articles #4 appears to be feedback from users, but Issues is not the best place for that. Maybe we can consider enabling GitHub Discussions for this repo.

I "watch" this repo for all activity to learn about any new resources added or any issues with existing resources. Seeing these empty issues being created is a waste of time for everyone involved. The only thing in our control is to make it more difficult to accidentally creating empty issues.
