Pull Request Overview

This PR reconfigures CI pipelines for the 6.0 release branch to properly handle pull requests, commits, and scheduled runs. The changes separate PR validation from commit-based CI triggers and establish distinct scheduled runs for GitHub and ADO branches.

Key Changes:

• Added dedicated PR trigger configuration to validate changes against the release/6.0 branch
• Separated commit triggers for release/6.0 and internal/release/6.0 branches with batch processing
• Updated scheduled runs from Saturday to Sunday with separate schedules for GitHub (release/6.0) and ADO (internal/release/6.0) branches
