v2: Example logging configuration needs to be updated

[scottgerring]

In the v2 branch, in the log4j2.xml files in each of the examples, we still reference LambdaJsonLayout:

powertools-lambda-java/examples/powertools-examples-parameters/src/main/resources/log4j2.xml

Lines 3 to 7 in fb14bcf

	<Appenders>
	<Console name="JsonAppender" target="SYSTEM_OUT">
	<LambdaJsonLayout compact="true" eventEol="true"/>
	</Console>
	</Appenders>

We need to update this to reflect the logging changes:

powertools-lambda-java/docs/core/logging.md

Lines 211 to 215 in fb14bcf

	<Appenders>
	<Console name="JsonAppender" target="SYSTEM_OUT">
	<JsonTemplateLayout eventTemplateUri="classpath:LambdaJsonLayout.json" />
	</Console>
	</Appenders>

Weird, this is super old... same problem in serialization example and tracing tests

@scottgerring we can close this as the changes are already merged #1545

Yes!
