What is the current behavior?

The CI action for the Automated app fails with a bunch of errors like these ones:

 ERROR in ./src/main.ts 8:0-69
Module not found: Error: Can't resolve '@nativescript/core' in '/Users/runner/work/NativeScript/NativeScript/apps/automated/src'

(example build: https://github.com/NativeScript/NativeScript/actions/runs/4204462364/jobs/7311437908)

What is the new behavior?

The workflow has been updated to use latest version of each action (bundled in here, but unrelated to the failing workflow).

We are setting the install-links=false flag to force linking file: referenced packages.

Background of the issue:

• npm 9.0 changed install-links value to be true by default
• GitHub Actions updated the macos environment from npm 8.9 to 9.3.1 recently

About the install-links flag from the NPM docs:

When set file: protocol dependencies will be packed and installed as regular dependencies instead of creating a symlink. This option has no effect on workspaces.

So essentially, we were running npm pack in packages/core and then installing the pack into apps/automated, however this pack didn't contain neither the .ts files (they are not part of the public package) nor .js files, since we are not building core in this workflow - we instead rely on the source files (.ts files) which are only included when we link the dependency instead of packing it.
