[ Bug ] Modify IAM template file to remove hyphens

[gwright99]

Issue reported from the field in Dec 2024 re how some entries are defined in permissions.md:

In the Sid "InteractWithTFPrefixedIAMResources" section, the current format includes dashes (-) at the end of the resource strings, which led to errors in my case. The Terraform resource aws_iam_role.ec2 creates a role with underscores (_) instead of dashes in its name, causing a mismatch.
...
I would recommend removing the trailing dashes to align with Terraform's role naming convention:

"Resource": [
"arn:aws:iam::AWS_ACCOUNT_REPLACE_ME:role/tf-APP_NAME_REPLACE_ME-",
"arn:aws:iam::AWS_ACCOUNT_REPLACE_ME:policy/tf-APP_NAME_REPLACE_ME-",
"arn:aws:iam::AWS_ACCOUNT_REPLACE_ME:instance-profile/tf-APP_NAME_REPLACE_ME-*"
]
