[Enhancement]: Support for all AWS FIS Action targets

[ebarros29]

Description

AWS FIS has support for many Action targets according to it's documentation, however the aws_fis_experiment_template resource does not support the below action targets:

• Auto Scaling groups – Amazon EC2 Auto Scaling groups
• Buckets – Amazon S3 buckets
• Encrypted global tables – Amazon DynamoDB; global tables encrypted with a customer managed key
• ReplicationGroups – ElastiCache Redis Replication Groups
• TransitGateways – Transit gateways

Error message after executing terraform plan:
