Rule proposal: `prefer-number-is-safe-integer`

[fisker]

Description

I think in all cases use Number.isInteger, Number.isSafeInteger should be preferred.

Examples

// ❌
if (!Number.isInteger(x)) {}

// ✅
if (!Number.isSafeInteger(x)) {}

Sounds useful. The only problem I can think of are the checks assuming the inverse case is not an integer.

if (Number.isInteger(x)) {

} else {
	// Assumes this is not an integer.
}
