Improve clarity and prerequisites in "Deploy/Develop with Kind" documentation

Description

While reviewing the "Deploy/Develop with Kind" guide, I found that some setup steps could be clearer for new users.

Issues Identified
Prerequisites (e.g., Docker, kubectl, permissions) are not clearly listed
Some commands (e.g., make docker, kind load docker-image) lack explanation
Minor grammatical issues (e.g., "specified" → "specify")
Proposed Solution
Add a short "Prerequisites" section
Include brief explanations for key commands
Fix minor wording issues
