[Feature] Add type, icon and use_container_width properties to buttons

[azabicki]

Describe the feature

Hi there,
Thanks for creating and sharing your project!

I noticed that the buttons and submit_buttons are missing some properties, such as type, icon, and use_container_width. I believe these were also requested in other issues (e.g., #200, #212).

So I thought this might be a great opportunity to contribute :)

Use case

It would be great to have the same styling options for buttons as in Streamlit.

I will open a PR in a minute.
