BigInt support for Number functions

[mcintyre94]

Feature Request

Description: For each Number related matcher, support BigInt input values

For example this test should pass:

test('passes when value is a number', () => {
  expect(1n).toBeNumber()
});

This matches Jest behaviour: jestjs/jest#8382

test('passes when value is a number', () => {
  expect(1n).toBeGreaterThan(0)
});

Possible solution: Probably need to update each matcher on a case-by-case basis. Initial thoughts for each, might not cover everything:

• toBeNumber is just a case of updating the typeof check
• toBeNaN should be able to be fixed by changing from isNaN to Number.isNaN which supports bigint correctly
• isFinite will probably need to cast its input to Number since Number.isFinite(123n) is false for some reason
• toBePositive uses isNaN, probably just needs updating to Number.isNaN 🤞
• toBeNegative seems to work (should add tests though to make sure it keeps working!)
• toBeEven probably needs to check the type, and use 2n instead of 2 for bigint (can't do bigint % number, or vice versa)
• toBeOdd same as toBeEven
• toBeWithin seems to work
• toBeInteger will probably need to cast its input to Number since Number.isInteger(123n) is false for some reason
