fix: update validation for throughput capacity

[stefanfreitag]

Description

Update the validation for the argument throughput_capacity when creating an aws_fsx_windows_file_system resource.

The current validation allows values between 8 and 2048. Actually,

• only a small subset of values inside this range is allowed
• larger values are also fine in some regions.

Here an example output when a value of 2040 is specified:

 Error: creating FSx for Windows File Server File System: operation error FSx: CreateFileSystem, https response error StatusCode: 400, RequestID: 39b44ab9-daca-46f1-a6c0-ec8a64c639d1, BadRequest: Invalid desired throughput capacity value provided: 2040 MB/s. Please refer to the performance guide (https://docs.aws.amazon.com/fsx/latest/WindowsGuide/performance.html) when selecting a value.

The documentation is updated and no longer mentions in power of 2 increments as this in no longer true for values > 2048.
