patch: Fix lambda role logic

[jamengual]

what

• Fix logic in iam_role policy attachment.

why

• because is fails with :

│ 
│   on .terraform/modules/sample_lambda.lambda_function/iam-role.tf line 35, in resource "aws_iam_role_policy_attachment" "vpc_access":
│   35:   count = local.enabled && try(length(var.vpc_config), 0) > 0 ? 1 : 0
│ 
│ The "count" value depends on resource attributes that cannot be determined until apply, so Terraform cannot predict how many instances will be created. To work around this, use the -target argument to first apply only the resources that the count depends on.```
