Summary of Changes

This is a follow-up to #46186. The development dependency mysql was upgraded to mysql2 for GitHub Actions based System Tests. But the used version as currently five security vulnerabilities. This PR upgrades to the current version of NPM packet mysql2 to fix the security vulnerabilities. As it is a developer dependency, we do not ship its code to end users, so it is not that critical, but we have to fix it.

Updated to current version with npm install -D mysql2@3.15.3

Testing Instructions

1. Code review
2. You can check the mysql2 security vulnerabilities:
