Improve experience on writing unittests (#570)

While working on #409, I noticed that some unittests contains either
invalid assertion methods (`isNotEmpty`) or invalid properties (`any`)
for a specific assertion method (`notContains`).

As our tests pass - and I have ensured that they can fail - this seems
related to the YAML schema validation in the IDE.

I've noticed that `isNotEmpty` was replaced by `isNotNullOrEmpty`[^1]
in version v0.3.2[^2]. At least from a schema validation point of view.
It is still working. Maybe deprecated? I don't know.

Regarding the `any` property, the documentation seems incorrect. I've
filed a PR for it[^3]. As soon as that PR is merged and released, we
could probably validate the test YAML files in our PR workflow.

Last, since we renovate the used helm-unittest version, we should also
renovate the used YAML schema file.
