Keeping the given content and the selected action in AskActionMessage function

[NaguiHW]

I was developing a kind of admin manager view for a user with admin role and this admin can upload more data and delete data from the database and I was using the AskActionMessage function and I found that is a bit confusing only show the default message: **Selected:** {res["label"] when we are asking more than 1 action to the user.

This is why I created this pr to solve this issue.

This is an example:

If you see the 2 first answers, you don't know the context, but in the third one you can see the question and the action selected.

I just added an optional parameter keep_content that is a boolean and is False by default.

Of course this is useful only if we are going to ask more than 1 action. Like I said when I was developing this type of view, like an admin panel, I have to use at least 6 AskActionMessage.

I know that we have @cl.action_callback("action_button"), but is not the same, because the input query is not disabled and is not that clear how we can delete all other action buttons if we have more than 1 action.

@NaguiHW Thanks for this great contrib! Sorry it took us quite a while to get back to you!

Does your contrib has any implications for the documentation? If so, could you please propose any relevant changes to the docs

Lastly, I want to test this! Any chance you could supply me a minimal test project and basic testing instructions so I can observe the before/after difference so I can manually reproduce the issue and observe your proposed solution? ❤️
