Pull request overview

This PR updates the SECURITY.md file to match the standardized Microsoft security documentation template from the microsoft/.github repository, as requested by the security team. The changes streamline and modernize the security reporting instructions.

Key changes:

• Simplified organization description by removing specific GitHub organization examples
• Removed the PGP key email submission option
• Updated follow-up instructions with more detailed guidance, including messaging functionality and additional resource links

The markdown link has an inconsistency: the display text shows https://msrc.microsoft.com/report/vulnerability but the actual URL is https://msrc.microsoft.com/report/vulnerability/ (with a trailing slash). Consider making these consistent by either:

• Adding the trailing slash to the display text: [https://msrc.microsoft.com/report/vulnerability/](https://msrc.microsoft.com/report/vulnerability/)
• Or removing the trailing slash from the URL: [https://msrc.microsoft.com/report/vulnerability](https://msrc.microsoft.com/report/vulnerability)
