fix: toHaveTextContent supports interpolated variables

[jeremyshearer]

What:

Fix a bug where text content that gets split into an array does not get evaluated by the toHaveTextContent matcher.

Why:

There's a test case in the PR, but this test case currently fails in master:

    const variable = 'variable';
    const { container } = render(<Text>With a {variable}</Text>);

    expect(container).toHaveTextContent('With a variable');

    // Expected element to have text content:
         // With a variable
    // Received:

How:
The bug was in treating all array elements as react nodes that had a path of ['props', 'children'] that could be traversed to get the text content. The fix is to pass the element directly into the recursive getText call and let the conditional logic determine how to extract the text.

@jeremyshearer thanks for opening this PR. Looks good, I just left a comment.

I was about to comment in #52 that it didn't worked for interpolated variables, but you've already fixed it XD

I'm not sure if it helps, but this change works for me :D

@brunohkbx Thanks for taking a look! I have applied your excellent suggestion. Please let me know if you see anything else that needs to happen to get this merged in.

I'll try to take a look at it today and starts a draft
