fix: update node image.endpoint config structure

Changes

• Astro 5 made changes to the image endpoint config
• This PR makes those structure changes in the node adapter
• For whatever reason, the old state of the config only created issues when built and executed in a docker container

Fixes #13183

Testing

• Tested locally (with some difficulty) by heavily modifying the SSR example and running it locally in a docker container

Docs

• N/A

@lee-arnold are you still interested in the PR?

Yes, apologies - chaotic start to the week. Will get on the changeset now.

If you have any, I would love some advice on what you think might be an appropriate test.
