feat: add plugin support for the react component

[AceTheCreator]

This PR introduces a plugin system for the AsyncAPI React component, enabling developers to extend and customize the documentation renderer with custom components, event handling, and dynamic plugin management.

Changes

• New AsyncApiPlugin interface and PluginAPI for plugin development
• Component registration in PluginSlot.OPERATION slots
• Event system: on(), off(), emit() for inter-plugin communication
• Dynamic plugin registration/unregistration at runtime
• Priority-based component ordering (higher priority renders first)
• Full TypeScript support

const plugin: AsyncApiPlugin = {
  name: 'my-plugin',
  version: '1.0.0',
  install(api: PluginAPI) {
    api.registerComponent(PluginSlot.OPERATION, MyComponent, { priority: 150 });
    api.on('event-name', (data) => console.log(data));
  }
};

<AsyncApi schema={schema} plugins={[plugin]} />
