fix(expect): objectContaining should recurse into sub-objects

[ioancole]

Addressing bug report #10462. According to the docs, objectContaining should apply in a recursive sense, however it doesn't seem to do this currently.

Summary

This change will make objectContaining work recursively into sub-objects.

Test plan

Included a unit test for the new behavior, and confirmed that all older tests still pass.

Wonderful, thanks!

Ergh, seems CI is unhappy 😅 Would you be able to take a look?

[ioancole]

Hey Simen, thanks for looking at this so quickly. The only check failing now is the windows-latest test run on a seemingly completely unrelated DOM test, and this check passed on a previous push to this PR. Is there a way to re-run the CI pipeline? I think this will pass on a re-run. Thanks!

[SimenB]

Yeah, that failure looks like flake. I'll retrigger CI 👍

[SimenB]

@ioancole sorry, this seems to produce a type error. Could you take a look?

[ioancole]

Hey! It's fixed now. Thanks again

[SimenB]

Thanks @ioancole!
