[Ivy] @ngrx/store-devtools included in bundle in production mode

Minimal reproduction of the bug/regression with instructions:

import { StoreDevtoolsModule } from '@ngrx/store-devtools';

import { environment } from 'environments';

const STORE_DEV_TOOL_MAX_AGE = 25;

@NgModule({ imports: [ // other imports StoreDevtoolsModule.instrument({ logOnly: environment.production, maxAge: STORE_DEV_TOOL_MAX_AGE, }), ], }) export class AppModule { }

Expected behavior:

Not included in bundle in production mode;
