TestcontainersExtension should be public to allow ordering extension in JUnit5

[loicmathieu]

When we use multiple JUnit5 extensions, the way to order them is via the @ExtendsWith({FirstExtension.class, SecondExtension.class}) annotation.
But TestcontainersExtension is not public so we can only use the @Testcontainers annotion and we are not able to order the extension.

See the following documentation on JUnit5: https://junit.org/junit5/docs/current/user-guide/#extensions-registration-declarative

Some microservices frameworks have extension to start the application for integration testing, whe using test containers, we need to be sure that the testcontainers extension run first to start the containers before the apps starts.

I am not sure but maybe have a look at the @RegisterExtension Junit5 Annotation. It allows you to specifiy any Order.

here: https://junit.org/junit5/docs/current/user-guide/#extensions-registration-programmatic

I also need some setup like the registry authentication config and therefore just place the @ExtendsWith before the @Testcontainers Annotation at top level class.

@HaMatthias surely I can use @RegisterExtension instead of @ExtendsWith, but in both cases the TestContainersExtension needs to be public in order to use them.

If you believe this is a mistake, please reply to this comment to keep it open. If there isn't one already, a PR to fix or at least reproduce the problem in a test case will always help us get back on track to tackle this.

@HaMatthias @bedla send a PR for this. I still think it is useful ...

If you have any concrete examples of what you're looking for, that would be helpful!

@hmatt1 I thought I clearly describe the use case: having the ability to order JUnit extensions used together on the same test case. The documented way to do this from the JUnit guide is to use @ExtendsWith({FirstExtension.class, SecondExtension.class}) which is not possible as the TestcontainersExtension is not public.

I just want it to be public to be able to manage extensions order as it is intended.
