🩹 [Patch]: Use GitHub App again and some log and file formatting

[Marius Storhaug (MariusStorhaug)]

This pull request updates the workflow and script for automating the FontsData update process. Key changes include integration with GitHub App credentials, enhanced error handling, and formatting updates for better readability. The changes also streamline the process for detecting updates, committing changes, and creating pull requests.

Workflow updates:

• .github/workflows/Update-FontsData.yml: Added GitHub App credentials (ClientID and PrivateKey) for secure authentication during the update process. Removed permissions as these grant the GITHUB_TOKEN permissions, which is no longer used.

Script enhancements:

• scripts/Update-FontsData.ps1: Improved command execution to capture output and handle multiline results, returning formatted output when applicable.
• scripts/Update-FontsData.ps1: Updated JSON formatting for FontsData.json to include indentation for better readability.
• scripts/Update-FontsData.ps1: Enhanced logging and messaging, including clearer notices for no updates, summary of changes, and improved pull request titles and descriptions. [1] [2]
