[Enhancement]: Support zonal shift for ALBs

[cdaniluk]

Description

aws_lb supports zonal shift for NLBs but not ALBs. Per ARC documentation, the same attribute is valid for ALBs and NLBs.

Suggest changing:

terraform-provider-aws/internal/service/elbv2/load_balancer.go

Line 773 in eb41f1a

loadBalancerTypesSupported: []awstypes.LoadBalancerTypeEnum{awstypes.LoadBalancerTypeEnumNetwork},

to:

		loadBalancerTypesSupported: []awstypes.LoadBalancerTypeEnum{awstypes.LoadBalancerTypeEnumApplication, awstypes.LoadBalancerTypeEnumNetwork},

Tests would need to be updated as well. Happy to submit a PR if helpful.

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

• aws_lb

Potential Terraform Configuration

No change to Terraform configuration or docs are required.
