Remove unnecessary 'val' parameter name in client->_event() calls

- share.md: Change client->_event( val = `BUTTON_POST` ) to client->_event( `BUTTON_POST` )
- app_state.md: Change client->_event( val = `BUTTON_POST` ) to client->_event( `BUTTON_POST` )

When only the val parameter is used, the parameter name can be omitted
