Enhance Release Notes Detection in PR Title

[miroslavpojer]

Announcement: This Issue is waiting for some end-users to be implemented.

Description

Currently, release notes detection only checks the pull request body for the presence of correctly formatted release notes. We may want to extend the possible location to PR title.

Reasoning

Some contributors may include brief release notes or a summary of changes in the PR title. Detecting release notes in the PR title ensures that these notes are recognized if not present in the body.

Proposed Changes

• Update the action logic to check the PR title if configured.
• Validate that if the PR title contains the phrase Release Notes:, and use the subsequent text.

Example of title usage

Release Notes: Added functionality for user notifications
