Suggestion: Allow node_modules to be included in deployments with railway up

[mikebywaters]

Problem

railway up ignores node_modules by default:
https://github.com/railwayapp/cli/blob/2d2a8c14385368662059e2781c4d2412aef419a9/src/commands/up.rs#L184C34-L184C46
but there are use cases where deploying the contents of node_modules is desirable, eg. when the dependency install is being done as part of another CI pipeline (eg. GitHub Actions, Buildkite) and isn't part of the Docker container.

Potential solutions

1. Remove the default behaviour
2. Provide a flag that enables the behaviour to be bypassed

Hey @mikebywaters!
Just yesterday we got the CLI image published to ghcr. Now you can build everything inside of CI environment of your choice and then push the result to railway with a minimal dockerfile or nix config
