Code Review
This pull request refactors the Gemini model prompt in issue-labeling.ts by separating the system instructions from the user content (issue title and body) and utilizing the systemInstruction configuration parameter. The feedback suggests using optional chaining and nullish coalescing (?. and ?? '') instead of non-null assertions (!) to robustly handle cases where the issue title or body might be null or undefined.
