[CI] Prevent duplicate PR entries in release notes

[leecalcote]

Current Behavior

Release notes are showing PRs multiple times when they have labels matching different categories (e.g., a PR with both kind/feature and area/docs appeared in both Features and Documentation sections).

Desired Behavior

Configure the release-drafter workflow to ensure that each merged pull request is only included once in the draft release notes.

Implementation

1. Add no-duplicate-categories: true to .github/release-drafter.yml

Here is the PR #33

• no-duplicate-categories is not a supported setting in Release Drafter. PRs are matched to all categories based on their labels, and there’s currently no built-in way to restrict a PR to appear in only the first matching category.

• So we will be closing this issue as the option is not supported in the current Release Drafter configuration.
