GH Issue and PR templates

[samyakshah3008]

Description:

• Added a few standard issue ticket templates when anyone creates a new GH issue. This PR fixes Feat: Setup PR and Issue templates #373

✅ Added Issue templates for:

1. Bug Report
2. Feature Request
3. Chore task
4. Continuous Integration (CI) DevOps task
5. Documentation task
6. Any other questions

✅ Added PR template

Impact of this PR:

• Any new/existing contributor who creates an issue ticket, will cover all the potential points without missing anything. I have seen in a few orgs that people often misses out on adding "descriptive" content in the issue raised. And then gets follow up questions on that reported issue.
• To save time for maintainers who assigns issue to contributors, this will be quite helpful.
