provider/aws: Fix panic when passing statuses to aws_acm_certificate (#…

…9990)

Fixes #9989

When passing a list of statuses to the acm_certificate data source, we
were trying to cast a schema.TypeList directly to []string

We need to do it via an []interface{} and then cast to string when
ranging over the results. Without this, we get a panic
