Greptile Summary

This PR fixes a broken Code of Conduct link in all three GitHub issue templates (bug.yaml, documentation.yaml, feature.yaml). The old links incorrectly pointed to github.com/appwrite/appwrite, while the new links correctly reference github.com/appwrite/sdk-generator/blob/master/CODE_OF_CONDUCT.md, which exists in this repository. The change is applied consistently across all templates and looks correct.

Confidence Score: 5/5

This PR is safe to merge — it is a simple, correct link fix with no code logic changes.

The change is minimal and mechanical: three identical one-line link corrections in YAML config files. The target file (CODE_OF_CONDUCT.md) was confirmed to exist in the sdk-generator repo. No logic, code, or behavior is affected.

No files require special attention.
