S3 backend override tf code generated incorrectly

PR

The shared_config_files field is being rendered as a string instead of as a set of strings.

terraform {
  backend "s3" {
    access_key = "test"
    bucket = "...tf-state"
    dynamodb_table = "terraform-state-locks"
    encrypt = true
    endpoints = {
      s3 = "http://s3.localhost.localstack.cloud:4566"
      iam = "http://localhost:4566"
      sso = "http://localhost:4566"
      sts = "http://localhost:4566"
      dynamodb = "http://localhost:4566"
    }
    key = ".../terraform.tfstate"
    profile = "...-terraform"
    region = "us-east-1"
    secret_key = "test"
    shared_config_files = "['~/.aws/config']" <-- Renders it as a string.
    skip_credentials_validation = true
    skip_metadata_api_check = true
  }
}

This part in tflocal is wrong for lists:

if isinstance(value, bool):
    value = str(value).lower()
elif isinstance(value, dict):
    # Special handling for dictionaries
    ...
else:
    value = f'"{str(value)}"'

should have an elif for list like:

elif isinstance(value, list):
    value = json.dumps(value)

@wisefool769 thanks for digging into it! Would you be up to filing a PR to fix this? :)

@alexrashed this worked better in my tests: #66
