what:
- adds price rule operators when doing price calculations
- rules now accepts a key where the value can be an array of objects `({ operator: string, value: number })`
- validation for available types of operator and value to be a number
```
await service.createPriceSets({
prices: [
{
amount: 50,
currency_code: "usd",
rules: {
region_id: "de",
cart_total: [
{ operator: "gte", value: 400 },
{ operator: "lte", value: 500 },
]
},
},
]
})
```
- price calculations will now account for the operators - lte, gte, lt, gt when the price context is a number
