This commit improves the edited/moved tippy tooltip to now include a
second italic line: "Click to view history" This line is visible
only when 'realm_allow_edit_history' is true for any organization
settings. Additionally, the first line is changed to display
"Last edited today at 00:00 AM" The date is in lowercase if it
doesn't contain a number for example 'today' unless the first
alphabet is uppercase.
'tippy-zulip-delayed-tooltip' was used as a common class to
implement tippy tooltips in addition to other elements in the
'edited_notice.hbs' file. However, now we need to make some
changes in tippyjs inside the onShow function to decide whether
to show the second line of a tooltip or not. Therefore, we need
to use a unique class for the edited_notice tooltips. Hence, removed
the 'tippy-zulip-delayed-tooltip' class from the edited_notice.hbs
file and used the 'message_edit_notice' class instead.
Fixes: #23075
