Adding eventClick functionality about streamlit-calendar

[im-perativa]

Hi @jovi-s . eventClick functionality is enabled by default (check demo at https://calendar-component.streamlit.app/ and try to click an event).

Keep in mind that the callback usage in streamlit is different per this guide.

The example app from the template shows how bi-directional communication is implemented. The Streamlit Component displays a button (Python → JavaScript), and the end-user can click the button. Each time the button is clicked, the JavaScript front-end increments the counter value and passes it back to Python (JavaScript → Python), which is then displayed by Streamlit (Python → JavaScript).

So if you want to add some action in streamlit based on the callback value you need to implement it in streamlit logic.
