Reinstate Spring for GraphQL auto-configuration

This commit adds the Spring for GraphQL auto-configuration back
into Spring Boot 3.0, now that a 1.1.0 release is scheduled with the
required baseline. This release also needs GraphQL Java 19.0 as a
baseline.

Closes gh-31809

+ * Annotation to perform GraphQL tests focusing on GraphQL request execution without a Web

+ * <p>
+ * The annotation disables full auto-configuration and instead loads only components
+ * relevant to GraphQL tests, including the following:

+ * <li>{@code @Controller}
+ * <li>{@code RuntimeWiringConfigurer}
+ * <li>{@code @JsonComponent}

+ * <li>{@code DataFetcherExceptionResolver}

+ * <p>
+ * The annotation does not automatically load {@code @Component}, {@code @Service},
+ * {@code @Repository}, and other beans.
+ * <p>
+ * By default, tests annotated with {@code @GraphQlTest} have a
+ * {@link org.springframework.graphql.test.tester.GraphQlTester} configured. For more
+ * fine-grained control of the GraphQlTester, use
+ * {@link AutoConfigureGraphQlTester @AutoConfigureGraphQlTester}.
+ * <p>
+ * Typically {@code @GraphQlTest} is used in combination with
+ * {@link org.springframework.boot.test.mock.mockito.MockBean @MockBean} or
+ * {@link org.springframework.context.annotation.Import @Import} to load any collaborators
+ * and other components required for the tests.
+ * <p>
+ * To load your full application configuration instead and test via
+ * {@code HttpGraphQlTester}, consider using
+ * {@link org.springframework.boot.test.context.SpringBootTest @SpringBootTest} combined
+ * with {@link AutoConfigureHttpGraphQlTester @AutoConfigureHttpGraphQlTester}.
