[Enhancement]: JUnit CloseableResource deprecated

Proposal

JUnit 5.13 has deprecated the CloseableResource interface and now recommends users to instead implement the AutoCloseable interface.
See https://docs.junit.org/5.13.3/user-guide/index.html#extensions-keeping-state-autocloseable-migration.

As it stands, right now JUnit 5.13+ now spews the following warning to the console when executing tests which use the TestContainers JUnit extension, so remedying this with their suggested change would be appreciated:

WARNING: Type implements CloseableResource but not AutoCloseable: org.testcontainers.junit.jupiter.TestcontainersExtension$StoreAdapter

• It sounds like it would just require changing the method signature at https://github.com/testcontainers/testcontainers-java/blob/1.21.3/modules/junit-jupiter/src/main/java/org/testcontainers/junit/jupiter/TestcontainersExtension.java#L263 ?

Yes, I believe all that is needed to denote it implements AutoCloseable, something like this:

private static class StoreAdapter implements CloseableResource, AutoCloseable {
...
