Adding issue templates and auto-labels

[anawishnoff]

Problem

Making overall changes to the repo to improve our triage process.

Solution

Adding new issue templates so users can file more specific, actionable issues. Also adding auto-labeling functionality to label new issues as needs-triage when they get opened so that we can properly triage.

Type of Change

• [ ] Bug fix (non-breaking change which fixes an issue)
• [ ] New feature (non-breaking change which adds functionality)
• [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)
• [ ] This change requires a documentation update
• [ ] Infrastructure change (CI configs, etc)
• [x] Non-code change (docs, etc)
• [ ] None of the above: (explain here)

Test Plan

Tested the auto-labeler in the Go SDK repo

Just run prettier on the files and push them back up (lmk if you don't know how to do that, happy to show you!)
