Add doorbell press event support for Doorbell 2S-76C3

[Guido117]

Hello,

Thank you for your continuous work on the Imou-Home-Assistant integration! I am using the Doorbell 2S-76C3 and would like to request a feature enhancement. Specifically, I would like the integration to support detecting when the doorbell is pressed, exposing this event to Home Assistant.
I am willing to provide further details or help with testing if needed. Thank you for considering this enhancement request!

Same here! Would love to see in Home Assistant when the doorbell button is pressed.
