feat: generate deployment group name

[samchungy]

Proposed changes

• Generates a Deployment Group Name in the format of ${stackName}-${logicalId} to avoid a circular dependency when used with the aws-alerts plugin.
• Reference generated group name in IAM role instead of using !Sub to reference, thereby removing the circular dependency.
• Fix lint issues
• Ran npm audit fix

Resolves #127
Resolves #114
