Synthetics push command doesn't detect changes in imported files

[awahab07]

Agent Version: 1.3.0

Summary

When using the push command, Synthetics CLI doesn't react to code changes in the imported files, e.g.

import { journey, step, monitor, expect } from '@elastic/synthetics';
import { prepare } from '../helpers/helpers';

journey('Journey Name', ({ page, params }) => {
  step('Step 01', async () => {
    await prepare(page);
  });

  ...
});

for the above journey, any changes in the prepare will not mark the monitor as edited and push will not push the updated monitor to Kibana, unless the journey file itself is modified.

Steps to reproduce

1. Create an example journey in a Synthetics CLI project.
2. In one of the steps, make a valid operation inside a helper method imported from an outer file e.g. ../helpers/helpers'.
3. Push the monitor via

   SYNTHETICS_API_KEY=<API-KEY> npm run push
   

4. Make a change in the imported helper method and push again.
5. You'll notice that the changes in the helper method won't be pushed as the modification is not detected by the CLI. If there were no other modifications, CLI will show:

    > Monitor Diff: Added(0) Updated(0) Removed(0) Unchanged(1)
   

Expected behavior

Any change in any imported file should mark that journey file as modified, even if the journey file isn't changed. Or if possible, mark only those journeys as modified which are consumers of imported components that have been modified.

Post-FF Testing LGTM

Added an import from an external file to my example project monitor file:
