[Bug] removeItems function not working

[armata99]

Describe the bug
removeItems function does not remove anything from store and returns undefined instead of boolean.

To Reproduce

1. create a test file
2. add below content and run the tests

import {isLoaded} from 'react-native-mmkv-storage';


describe('bug repro test', () => {
  //from docs
  beforeEach(() => {
    // Install the in-memory adapter
    let mmkvMock = require('react-native-mmkv-storage/jest/dist/jest/memoryStore.js');
    mmkvMock.unmock(); // Cleanup if already mocked
    mmkvMock.mock(); // Mock the storage
  });

  //from docs: Use the storage methods as needed. Everything is mocked now
  it('Mock bindings are installed', () => {
    expect(isLoaded()).toBe(true);
  });

  //my own test
  it('testing removeItems function', () => {
    const storage = new MMKVLoader()
      .setProcessingMode(ProcessingModes.SINGLE_PROCESS)
      .withInstanceID('instance')
      .initialize();

    // Store some items
    storage.setString('key1', 'value1');
    storage.setString('key2', 'value2');
    storage.setString('key3', 'value3');

    // Array with multiple keys
    const keysToRemove = ['key1', 'key2'];

    storage.removeItems(keysToRemove); //does not remove the 2 given keys

    const item1 = storage.getString('key1');
    const item2 = storage.getString('key2');
    const item3 = storage.getString('key3');

    expect(item1).toBeNull(); // Should be null but its not
    expect(item2).toBeNull(); // Should be null but its not
    expect(item3).toBe('value3'); // Should still be 'value3'
  });
});

Expected behavior
items with keys key1 and key2 should be removed from store but they don't. In other words, this test should pass.

Screenshots
not necessary

Platform Information:

• OS: it's happening in testing with jest. I didn't test it at runtime yet.
• React Native Version: 0.76.7
• Library Version ^0.11.2

Additional context
I rewrote my actual code to iterate over keys array and remove them one by one for now. It passes the test that way:)
Let me know if there is anything else you need to know.
