feat(pricing, types): add price rule operators to price calculations (#10350)

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
