errors in m6 solution due to naming mismatches

[mistwire]

1. m6 instances.tf line 17 errors out -> aws_subnet.subnet1.id should be aws_subnet.public_subnet1.id
2. m6 instances.tf line 18 errors out -> aws_security_group.nginx-sg.id should be aws_security_group.nginx_sg.id
3. m6 instances.tf line 40 errors out -> aws_subnet.subnet2.id should be aws_subnet.public_subnet2.id
4. m6 instances.tf line 41 errors out -> aws_security_group.nginx-sg.id should be aws_security_group.nginx_sg.id
5. m6 s3.tf doesn't match pluralsight video 😅 missing aws_iam_role & aws_iam_role_policy (which aren't needed as the env comes up fine)
6. m8 network.tf ran tf fmt
7. m8 renamed folder from globo-web-app-s3 to globo-webapp-s3 to match module call in s3.tf
