Pull Request Overview

This PR simplifies the Target Framework Moniker (TFM) setup by consolidating target framework definitions into a single location and removing conditional SDK version checks. The changes streamline the build configuration by eliminating the separate TargetFrameworks.props file and moving all target framework definitions to Directory.Build.props.

• Consolidated target framework definitions from conditional logic to a single static list
• Removed GitHubActionsTestLogger dependency and its usage
• Eliminated the separate TargetFrameworks.props file in favor of centralized configuration
