CI/CD - Create a gitAction template to deploy to AWS

[raksiv]

As a developer working with Nitric
I want access to a guide for github actions
Which I can use or clone to handle deployments to AWS

---

Coverage should be adequate with a guide for AWS, however mention that converting to some other cloud would be just as easy with minor tweaks.

The depth of any text created to support this documentation shouldn't be a long read -
Take inspiration from -
