using "unit_amount_decimal" leads to a change in "unit_amount" on every apply

[juliandm]

Reproduce:

• create a stripe price https://registry.terraform.io/providers/lukasaron/stripe/latest/docs/resources/stripe_price with the attribute "unit_amount_decimal" set
• create another dummy resource
• make changes to the dummy resource

You will see that the price resource is destroyed and recreated every time although nothing was changed in it

I was able to replicate the issue only when I put unit_amount_decimal as INTEGER value as opposed to FLOAT. Unfortunately, when unit_amount_decimal is set to INT (for example 1299) the Stripe SDK populates both values (unit_amount and unit_amount_decimal). Consequently, the Terraform state is confused.
