Typo in Task 3.1.1 and 4..1.1

[chandra-pexa]

Task 3.1.1 - https://github.com/btkrausen/hashicorp/blob/master/terraform/Hands-On%20Labs/Section%2004%20-%20Understand%20Terraform%20Basics/05%20-%20Intro_to_the_Terraform_Resource_Block.md#task-311

here it is mentioned as:
Run a terraform plan to see that this new Amazon S3 bucket will be added to our account. Don't worry, S3 buckets don't incur any fees unless you upload data to the bucket.

however this step is about deploying a security group not S3 bucket.

same in Task 4.1.1 - https://github.com/btkrausen/hashicorp/blob/master/terraform/Hands-On%20Labs/Section%2004%20-%20Understand%20Terraform%20Basics/05%20-%20Intro_to_the_Terraform_Resource_Block.md#task-411
