Can't build: .svelte-kit/tsconfig.json not found in container

[rmunn]

Describe the bug
I'm still seeing errors in the ui container about .svelte-kit/tsconfig.json not being found, and it's causing the containers to refuse to build in some cases. Eventually, I figured out that the .dockerignore file was excluding the entire .svelte-kit directory, but our other tsconfig.json files are referencing .svelte-kit/tsconfig.json so it needs to be there in order to prevent a chicken-and-egg problem.

this should be fixed by #1283, @rmunn can you confirm this is fixed for you now too?
