Need an option for turbo_reset_scroll_tag that goes to bottom for long lists / continuous scrolling

def turbo_refresh_scroll_tag(scroll = :reset)

has options to reset to the top-left or preserve the current scroll position which appears to be defined as an offset from the top of the page.

We have a scenario that does not seem to rare where there is a conversation being viewed in a page, and as new messages appear, we want them to be visible. Thus we would like to either refresh with scroll preserve acting as an offset from the bottom instead of top, or to just scroll to the bottom. We might be able to contribute such an option if you wanted to comment on preferred implementation
