Added tests for the sqrt() method in math.sw

[brandonsurh]

Description

Closes #5330

Previously, there were no tests for the sqrt() method in math.sw. This adds square root tests in the Rust test suite.
Other tests are found here:

• pow()
• log() and log2()

Will need help with adding assignees, adding labels, and requesting reviewers due to permissions. Lmk if anything else is desired with this change.

Nice, but these can be unit tests inside the stdlib, right? sway-lib-std/src/math.sw has an example already.

You are correct. I would actually prefer the tests for math.sw to be right in there too, but the pre-existing ones for pow(), log(), and log2() were made elsewhere. The reason I placed them in the Rust suite was to keep things uniform, but if desired I can move all of them into math.sw.

If possible I think makes more sense. Thanks! :D

Moved the tests for pow(), log(), and log2() into math.sw. Everything should be good on that front! However, may need to take a look at the failing checks.
