More Hamcrest Migrations for Number Matchers

[AlekSimpson]

What's changed?

This PR modifies the existing Hamcrest to AssertJ migration recipe to allow for more number matchers to be migrated.

What's your motivation?

#357

Anything in particular you'd like reviewers to focus on?

So I added support for closeTo but when I was looking through the list of matchers that related to numbers I couldn't find any others that weren't already supported. Maybe I'm not looking at the right documentation. Let me know if there were any other number matchers you were maybe expecting to see here.

Anyone you would like to review specifically?

@timtebeek

Have you considered any alternatives or workarounds?

At first I had created a dedicated recipe for closeTo but then realized the HamcrestMatcherToAssertJ recipe did most of what needed to be done already.

Thanks @AlekSimpson !

Quick follow up with 3a58f54 as we need to reference the recipe from Yaml before it's available to users.
