YassonParser does not implement JsonParser.currentEvent()

[nibsi]

Describe the bug
Version 2.1 of the Jakarta JSON Processing API added the method currentEvent() to the JsonParser interface. This method has a default implementation that throws UnsupportedOperationException.

Yasson implements JSON-P 2.1, but it does not override the default implementation for JsonParser.currentEvent().

This is likely an oversight. It's easy to miss new methods in interfaces when they have a default implementation.

To Reproduce

• Initialize a YassonParser parser.
• Call parser.next()
• Call parser.currentEvent()
• Observe that UnsupportedOperationException is thrown.

Expected behavior

• parser.currentEvent() returns the last event returned by parser.next().
