Revert back to getting the AWS role name from the URI with a small change (#49113)

- The role name and instance profile name _can_ be different
- Change the delimiter to `:` for keys that are discovered through the JSON parsing (which is not a valid delimiter for AWS IAM role names), this delimiter is still converted to underscore
- Now checks for the existence of that delimiter to remove the cases where the JSON keys are appended to the role name to find the role name
