Broken CFT link on Turbot Guardrails Enterprise Pre-Installation Checklist page

[skellish-turbot]

In section "6. Security Groups:", the link to the CloudFormation template is broken.
Currently points to:
https://github.com/turbot/guardrails-samples/blob/master/installation/security_groups.yml

but seems it should point to:
https://github.com/turbot/guardrails-samples/blob/main/enterprise_installation/guardrails_security_groups.yml
