Assertion parameter names are inconsistent between documentation and declaration ("value" vs. "actual")

[DavidAnson]

Documentation for the is assertion uses parameter names value and expected:

ava/docs/03-assertions.md

Line 124 in 6b63b1b

### `.is(value, expected, message?)`

Declaration for the same assertion uses parameter names actual and expected:

ava/types/assertions.d.ts

Line 190 in 6b63b1b

<Actual, Expected extends Actual>(actual: Actual, expected: Expected, message?: string): actual is Expected;

This is inconsistent. I think actual/expected is more clear and more common, so suggest standardizing on that pairing.

Sounds good to me. Would you like to open a PR @DavidAnson?

Please don't wait for me to send a PR, it's unlikely I'll have time for this soon.
