docs: AWS deployment (via Copilot CLI)

[JGalego]

This PR adds a one-liner deployment option to AWS via ECS + Fargate using the Copilot CLI.

Advanced

• *_API_KEY's can be managed securely with secrets
• custom resources (like IAM policies granting bedrock:InvokeModel* access to specific models) can be easily handled with addon templates

Thank you for your pull request and welcome to our community. We could not parse the GitHub identity of the following contributors: Joao Galego.
This is most likely caused by a git client misconfiguration; please make sure to:

1. check if your git client is configured with an email to sign commits git config --list | grep email
2. If not, set it up using git config --global user.email email@example.com
3. Make sure that the git commit email is configured in your GitHub account settings, see https://github.com/settings/emails
