Fix types for toSatisfy()/toSatisfyAll()

[tony19]

What

Bug fix in types

Why

The type for the arg of toSatisfy()/toSatisfyAll() is currently a predicate () => boolean, but the predicate itself has an argument (the item being iterated). The current signature causes an error in this TypeScript code:

expect(fooItem).toSatisfy((x: any) => x.myBoolProp); // Argument of type '(x: any) => any' is not assignable to parameter of type '() => boolean'.
expect(fooArray).toSatisfyAll((x: any) => x.myBoolProp); // Argument of type '(x: any) => any' is not assignable to parameter of type '() => boolean'.

Housekeeping

• Unit tests
• Documentation is up to date
• No additional lint warnings
• Add yourself to contributors list (yarn contributor)
• Typescript definitions are added/updated where relevant
