Cloud Run container can't be deployed because of devDependencies

[nhe23]

Describe the bug
Cloud Run Container does not start because of several issues with dependencies/scripts.

To Reproduce
1.Initialize svelte kit demo app
2. Add "svelte-adapter-firebase": "^0.6.3" as devDependency in package.json and configure the adapter as described in the docs
3. npm i
4. fix #53 locally & build the project
5. deploy to cloud run

Expected behavior
Cloud Run container should start

Screenshots

Additional context
Removing the devDependencies from the generated package.json in .mysitessr and removing all scripts but the 'start' script seem to fix this problem (At least the container is deployed).

The bug here is that the wrong package.json is being detected and used. Fix incoming.
