[NOREF] Remove host.docker.internal

[mynar7]

NOREF

Description

• host.docker.internal is a little bit of a pain on WSL, but also we can't use this with k8s, so I'm trying to strip the occurrences from our app. After this we just have the dev scripts that reference it.

How to test this change

• Run automated tests, test the document uploads locally.

PR Reviewer Guidelines

• It's best to pull the branch locally and test it, rather than just looking at the code online!
• When approving a PR, provide a reason why you're approving it
  • e.g. "Approving because I tested it locally and all functionality works as expected"
  • e.g. "Approving because the change is simple and matches the Figma design"
• Don't be afraid to leave comments or ask questions, especially if you don't understand why something was done! (This is often a great time to suggest code comments or documentation updates)
• Check that all code is adequately covered by tests - if it isn't feel free to suggest the addition of tests.
