fix(AgendaList): Allow user to control delay in scrollToSection

Solves #2194

I have set the default value to 0 because this is the expected default behaviour by most of the users to have no delay.

The delay is intentional, without which the debounce is meaningless... I understand the need to control this delay but the default should be kept to the current behavior otherwise this might cause issues to current implementations that relay on this delay.

I have updated the code as you suggested.
