Disallow number literals with zero fractions or dangling dots

There is no difference in JavaScript between, for example, 1, 1.0 and 1., so prefer the former for consistency.

This rule is fixable.

const foo = 1.0;

const foo = -1.0;

const foo = 123_456.000_000;

const foo = 1.;

const foo = 123.111000000;

const foo = 123.00e20;

const foo = 1;

const foo = -1;

const foo = 123456;

const foo = 1.1;

const foo = -1.1;

const foo = 123.456;

const foo = 1e3;
