Build on windows

[ppjgit]

Hi all, I tried to build the project on the Windows OS, but some unit tests failed because of whitespace. For example, this test:

           `@Test
	void formatTypeReferenceWithAnnotations() {
		var converter = new BeanOutputConverter<>(new ParameterizedTypeReference<TestClassWithJsonAnnotations>() {

		});
		assertThat(converter.getFormat()).contains("""
				```{
				  "$schema" : "https://json-schema.org/draft/2020-12/schema",
				  "type" : "object",
				  "properties" : {
				    "string_property" : {
				      "type" : "string",
				      "description" : "string_property_description"
				    }
				  },
				  "additionalProperties" : false
				}```
				""");
	}`

throws this exception:

`java.lang.AssertionError:

    }
  },

when I change `assertThat(converter.getFormat()).contains` to `assertThat(converter.getFormat()).containsIgnoringWhitespaces` this test works fine. There are many Unit tests like that and I don't know if somebody had the same issue.
