SECVULN-23992
The AWS access key that we're currently using for the github_actions-enos IAM user was created over 90 days ago. It should be rotated in order to mitigate against the risks of static credentials associated with using a service user. I have created a new key and added it to this repo's GH Actions Secrets. This PR replaces the old key. Once we have confirmed that introducing the new key hasn't broken anything, the old key will be removed from GH Actions secrets and AWS keys.

This is super noisy because of the linters. If it's not too much trouble I'd prefer disabling the new linters and merging only the necessary changes in.
