Updating Platform Accessories does nothing - method is not implemented
### Analysis

It is not possible to update platform accessories because the method `handleUpdatePlatformAccessories()` is not properly implemented:

https://github.com/homebridge/homebridge/blob/c25b3827a8ad2433083e93f3839255500d7478b1/src/bridgeService.ts#L388C3-L391

```
  // eslint-disable-next-line @typescript-eslint/no-unused-vars
  handleUpdatePlatformAccessories(accessories: PlatformAccessory[]): void {
    // Update persisted accessories
    this.saveCachedPlatformAccessoriesOnDisk();
  }
```

In this method, the array of `PlatformAccessory` objects is lost, as it is not used in the `handleUpdatePlatformAccessories()` method. The method just saves the currently cached platform accessories back to disc without updating anything.

Even worse, the method is commented with a `sweep-issues-under-the-rug` annotation:
```
  // eslint-disable-next-line @typescript-eslint/no-unused-vars
```

### Expected Behavior

`handleUpdatePlatformAccessories()` should take the passed in array of `PlatformAccessory` objects and update the appropriate cached accessories before saving them back to disk.
