resource/aws_api_gateway_deployment: Remove attributes that create stage

[gdavison]

Description

The resource type aws_api_gateway_deployment has three attributes, stage_name, stage_description, and canary_settings, that "silently" create a new stage that is not managed by Terraform, except that deleting the aws_api_gateway_deployment resource will also delete the stage. If stage_name refers to an existing stage, the stage will be modified.

We should prefer explicitly creating stages and assigning the deployment to the stage during creation or update. This will make it clear how the stage is managed. The ability to modify the stage using the deployment can also cause user confusion.

The attributes were deprecated in #39957.

Remove attributes:

• [ ] stage_name
• [ ] stage_description
• [ ] canary_settings

Affected Resource(s) and/or Data Source(s)
