feat(component): remove PushModule

BREAKING CHANGE:

The `PushModule` is deprecated in favor of the standalone `PushPipe`.

BEFORE:

```ts
import { PushModule } from '@ngrx/component';

@NgModule({
  imports: [
    // ... other imports
    PushModule,
  ],
})
export class MyFeatureModule {}
```

AFTER:

```ts
import { Component } from '@angular/core';
import { PushPipe } from '@ngrx/component';

@component({
  // ... other metadata
  standalone: true,
  imports: [
    // ... other imports
    PushPipe,
  ],
})
export class MyStandaloneComponent {}
```
