function eject does not work with inline functions without dependencies

[MichalKalke]

Description

When using function eject on inline function without dependencies the error appears about package.json

Simple inline function:

apiVersion: serverless.kyma-project.io/v1alpha2
kind: Function
metadata:
  name: f-status
spec:
  runtime: nodejs20
  resourceConfiguration:
    function:
      profile: XL
  source:
    inline:
      source: |
        module.exports = {
          main: function(event, context) {
            return 'Hello World!'
          }
        }

Steps to reproduce

kyma function eject f-status -d=path

Error:
  failed to call server

Error Details:
  failed to get runtime files for function 'default/f-status': failed to merge package.json: failed to unmarshal source package.json: unexpected end of JSON input

QA
Tested on my development shoot.

Now, function eject succeeds on the latest version of serverless (for JS and Python functions). On older versions of serverless, eject for JS functions fails.
