Local October CMS docker image & update to v4

Hi,

I’ve previously installed the interactive bash script to install my local testing environment, and now I’d like to update to v4 from v3. In the upgrade guide it says that first we need to make sure that we’re on PHP version 8.2. The docker image seems to be fixed to PHP v8.1.

I’ve tried pulling the image in again, but that too seems to be fixed to PHP v8.1.

What would be the best way to upgrade our local testing environment to October CMS v4?

Thanks.
