Integration Tests in SnippetIT.java Not Enabled after Recent Update

[0pdd]

The puzzle 3480-8a06dda4 from #3480 has to be resolved:

eo/eo-integration-tests/src/test/java/integration/SnippetIT.java

Lines 32 to 35 in daef5e0

	* @todo #3480:30min Enable integration tests after new release 0.56.3 to Maven.
	* Currently, integration tests fail because we are pulling eo-maven-plugin:0.56.2,
	* which has org.eolang.Attr, which is removed now. Don't forget to enable {@link ReadmeSnippetsIT}
	* too.

The puzzle was created by @yegor256 on 05-Jun-25.

Estimate: 30 minutes, role: DEV.

If you have any technical questions, don't ask me, submit new tickets instead. The task will be "done" when the problem is fixed and the text of the puzzle is removed from the source code. Here is more about PDD and about me.
