Addressing of critical and high vulerability alerts

The following three updates will cover the majority of issues detected; this report is for Red5 open source specifically and should apply to implementations utilizing the server.

• Spring 5.3.31
• Slf4j 2.0.11
• Logback 1.4.14

The update to Spring 6.0.x is delayed due to its requirement on JDK 17.
