Ember.onerror (and import of global Ember) is deprecated – all usage can probably be removed #16504

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

Reproduction Example/SDK Setup

See current usage of global Ember import here:

And usage of Ember.onerrorhere:

Steps to Reproduce

1. Go here https://deprecations.emberjs.com/id/deprecate-import-onerror-from-ember and see that importing global Ember is deprecated, and that there is no replacement for Ember.onerror

The usage of Ember.onerror has been discourged for a while, and not been in the docs since Ember v5.8 (May 15, 2024)

The current docs is to simply add an event listener to the 'error' event on window:

import fetch from 'fetch';
// ...
window.addEventListener('error', function(error) {
  fetch('/error-notification', {
    method: 'POST',
    body: JSON.stringify({
      stack: error.stack,
      otherInformation: 'exception message'
    })
  });
});

Expected Result

No imports from global Ember, specifically Ember.onerror since that is the only one used by Sentry. I guess having an event listener on the 'error' event is already handled by sentry, so the special logic for Ember.onerror can simply be removed, I think.

Actual Result

See reproduction.
