`Error: "EmberObject.create no longer supports.."` on Ember-4.12 addon - ONLY during embroider-safe scenario

### Environment

- Ember Version: ~4.12.0
- Ember CLI Version: ~4.12.2
- Ember CP Validations Version: ^5.0.0

### Steps to Reproduce

I updated my Ember Addon (v1) from `Ember 4.8` to `Ember 4.12`.

The addon is using `ember-cp-validations v5`.

This is what my `package.json` looks like:

```
"dependencies": {
...,
"ember-cp-validations": "^5.0.0",
...
},
"devDependencies": {
...,
"@babel/core": "^7.22.1",
"@babel/eslint-parser": "^7.21.8",
"@babel/plugin-proposal-decorators": "^7.21.0",
...,
"@ember-intl/cp-validations": "^5.0.0",
...,
"@embroider/test-setup": "^3.0.0",
...,
"ember-auto-import": "^2.6.3",
...,
"ember-qunit": "^6.2.0",
"ember-resolver": "^10.0.0",
"ember-source": "~4.12.0",
...,
"qunit": "^2.19.4",
...,
"webpack": "^5.0.0
},
"peerDependencies": {
"ember-source": "^4.8.0"
},
"resolutions": {
"@embroider/macros": "^1.12.2"
}
```

Everything works and all tests are passing, except when running the **embroider-safe** scenario where this error is thrown:

```
Error: Assertion Failed: EmberObject.create no longer supports defining computed properties. Define computed properties using extend() or reopen() before calling create().

at InternalFactoryManager.create (http://localhost:4200/assets/vendor.js:13726:25)
```

I understand that the Error itself `EmberObject.create no longer supports defining computed properties.` is a known issue, but I'm only getting it during the embroider-safe test scenario.
In the default scenario everything is working fine and all tests are passing.

Any help would be much appreciated 🙏
