Generated doc for springBoot-1.5 incorrectly claims Java 11, 17, 20 support

[dmuelle]

Describe the bug
The generated feature page for springBoot-1.5 lists the following under Supported Java Versions

• JavaSE-1.8
• JavaSE-11.0
• JavaSE-17.0
• JavaSE-20.0

But the feature only supports Java SE 1.8 and will throw an error message if you start an app with another version.

This page is part of the autogenerated doc and is not maintained by the ID team.

Expected behavior
The generated doc should list only JavaSE-1.8 under supported Java Versions

Additional context

per @tjwatson - the logic is in com.ibm.ws.springboot.support.shutdown.FeatureAuditor.postProcessEnvironment(ConfigurableEnvironment, SpringApplication) that puts a warning message if java 8 isn't used with springBoot-1.5
