Thin utility for SpringBoot 3 feature install causes NoClassDef

[cbridgha]

Describe the bug
When SpringBoot 3 feature is installed from a smaller package like kernel.. Its possible a jar used by the thin utility (ws-springbootutil.jar) won't be present, and will result in a NoClassDef exception thrown.

Steps to Reproduce
start with a smaller open liberty zip like openliberty-kernel-23.0.0.9.zip. Add the "springBoot-3.0" feature via the featureUtility command

Expected behavior
springbootutil.jar should run as expected with no issues

Diagnostic information:

• OpenLiberty Version: [23.0.0.9]
• Affected feature(s) [springBoot-3.0]

Issue caused by: dependent jar listed in the utility MANIFEST.MF is missing because the jar name changes depending on which version of the feature installed, it is either compiled for JavaEE or JakartaEE api's.
