[FIX] website_livechat: fix tour failing nondeterministically

This commit fixes the `website_livechat_chatbot_flow_tour` that was
failing in a nondeterministc way. This is due to the tour sometimes
taking more than `60` seconds which is the default timeout for python
tours.

Most of the time is consumed waiting for the user to finish its
multiline input. This issue is solved by shortening the delay to
consider the multiline input as done: from `10`s to `500`ms.

fixes runbot-24557

closes odoo/odoo#139034
