remove capacity_provider_strategy validation for aws_ecs_service resource

[dejanzele]

Description

When updating capacity_provider_strategy, update should happen in-place and not require recreate.

AWS provider Terraform docs mention a partial solution:

[capacity_provider_strategy](https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/ecs_service#capacity_provider_strategy)

(Optional) Capacity provider strategies to use for the service. Can be one or more.
These can be updated without destroying and recreating the service only if force_new_deployment = true
and not changing from 0 capacity_provider_strategy blocks to greater than 0, or vice versa.
See below.
Conflicts with launch_type.

The solution isn’t complete as changing base or weight to 0 triggers a recreate, but on AWS Console it can be updated without recreation.
