fix line-numbers for inline projects

Inline projects like example-react-app-e2e has the wrong line numbers in the playwright inspector.

Reproduction steps:

  1. type npx nx e2e example-react-app-e2e --debug in repository root
  2. look at the playwright inspector window

This problem only exist for inline projects.
Projects which were created in our e2e tests or in separate nx workspaces have correct line numbers in the playwright inspector (since playwright 1.38).
