JDK17 Record serialization should work with default settings (no need for JSON.Feature.USE_FIELD_MATCHING_GETTERS)

(off-shoot of #149 )

While #94 added support for serializing Java (17) and Groovy records, it requires explicit enabling of JSON.Feature.USE_FIELD_MATCHING_GETTERS (as per tests that now run).
But this should not be needed; code should automatically apply this setting for Record types.

Note that #148 adds introspection capability to detect if given class is a Record.
