Use OIDC to login to AWS

[lucacome]

Proposed changes

This PR updates the workflows to use OIDC to log in to AWS using short-lived tokens instead of static keys.

From the docs:

OpenID Connect (OIDC) allows your GitHub Actions workflows to access resources in Amazon Web Services (AWS), without needing to store the AWS credentials as long-lived GitHub secrets.
