LSP4Jakarta: Reduce the Code Duplication in Short names for Quick fixes

[anusreelakshmi934]

There is an existing method named getSimpleName defined in one of the classes. Update other classes that use similar methods like getShortName for obtaining the short name in quick fixes to instead use this getSimpleName method.

Additionally, refactor any classes that are still using the pattern annotationName.substring(annotationName.lastIndexOf('.') + 1) to extract the short name, so they also utilize the getSimpleName method.
