Broken instructions in /main/src/pages/docker/setup/initialize-docker.md

Re: https://developer.adobe.com/commerce/cloud-tools/docker/setup/initialize-docker#update-the-hosts-file-and-install-dependencies

For the "Update the hosts file and install dependencies" section...

These instructions refer to an old version of the "magento-cloud-docker" image (the page references version '1.3.5'; latest version is '1.4.5'), but the instructions don't work as the "init-docker.sh as asset" file isn't included on any recent releases (see: https://github.com/magento/magento-cloud-docker/issues/376).

Currently, you'll have to specify the 'image' parameter to get the latest images. I.e.

`curl -sL https://github.com/magento/magento-cloud-docker/releases/download/1.3.5/init-docker.sh | bash -s -- --php 8.4 --image 1.4.5`

Start with main/src/pages/docker/setup/initialize-docker.md and the linked “Update the hosts file and install dependencies” section. Check the referenced magento-cloud-docker release assets and issue #376, then update the documented command so it matches a supported release and verify the resulting instructions are accurate.
