Show how to assert that a specific layout was rendered in the render_template docs

[brunofacca]

Given that render_template can be used to assert that a specific layout was rendered, as in expect(response).to render_template('layouts/admin'), I suggest we include this in the docs. May I submit a PR?

[xaviershay]

yes please!

[brunofacca]

@xaviershay, please check the PR and let me know if it requires any adjustments.

@brunofacca I ran into this today and would love to see this merged. How can I help push this to the finish line?

@xaviershay Ping. :)

@knappe For the attached documentation PR to work it needs to actually assert the correct layout, or render the correct layout.

Okay, I'll see if I can work on this later tonight then.
