My use case:

• At the end of each test, save a video of the test in a file.
• It has to support the @RepeatedTest annotation and thus the computed file name must include the repetition index.

It seems the info is in RepeatedTestInvocationContext but there are 2 issues:

1. I don't know how to get access to that object in my afterEach, i.e. from an ExtensionContext. I guess I could use instanceof on the parent but it seems it's a TestTemplateExtensionContext so it wouldn't even work (and it feels hacky ;))
2. Even if I were able to get access to RepeatedTestInvocationContext it doesn't contain any API to get the current repetition. The only thing it offers is a custom displayName but having to parse that to get the repetition index doesn't feel right.
