fix: #50 support data-driven tests (it.each)

[lucax88x]

Still a draft, taking inspiration from neotest-jest

I had first to make the plugin tests works first, nio module was missing somehow and I had troubles on asserting command paths as you can see from my commit.

Then, I was finally able to get the first "piece" of code working, detecting the parametrized tests.

When I have some more time I'll check the other PR code how he handles the rest.

PS: the code is copy pasted from the PR above, I jet have to check what he wants to do!
