consistent-existence-index-check add option greater-than and none-zero

[ximex]

Description

I want to have the same option as explicit-length-check to choose between greater-than and none-zero.

none-zero could stay as default but if changed to greater-than it should behave as below

Fail

const index = foo.indexOf('bar');
if (index !== -1) {}

Pass

const index = foo.indexOf('bar');
if (index > -1) {}

Any reason you don't want === -1 and !== -1?

[ximex]

there is no hard reason. i know that it makes no different but it is more precise as value couldn't be below -1. and as the other rule has also the option i think this one could also get it

Use -1 to make the style be kept consistent

Otherwise, someone would write code like this

index >= 0
index > -1
index < 0
index <= -1

This makes the code confusing
