fix(actions): Deleting email templates on branch destroy

[andieswift]

Purpose

The plugin generating the email templates for each branch isn’t clearing the templates when the branch is deleted. As a result of this, the email templates created reached their limit and causing deploy failure in master (Mako’s Dev env). This is not a problem in prod because there is only one branch deployed to val/prod, but could potentially become an issue.

Approach

• adding a step to the destroy.yml "Remove CloudFormation templates"
• getting all the stacks with the template name (copying the code from the deploy.yml)
• then deleting each stack

Learning

• tried to use act which seemed promising, but for some reason didn't work with the deploy action & I decided just to check by manually running a delete
  • notes about act: needs docker installation

Screenshots

See, it works ✨
