Screenshots

Labels are in Italian.
"Oggi" => "today"

All the messages, both from the user and the bot, have timestamp around 2th February 3:30 PM, whereas the screenshot was done at around 3th February 11:15 AM.

Version

Custom ReactJS webchat, created using the "botframework-webchat" 4.8.0 npm package

Describe the bug

Activities related to "yesterday" are marked as "today". For example, with current timestamp "3th February 11:15 AM", an activity with timestamp "2th February 3:30 PM" is showed as "today" in the webchat.
The reason is that in the "useRelativeTimeFormatter.js" file the logic is done with delta time within 24 hours, regardless the current day.

Steps to reproduce

1. Go to the webchat
2. Generate some activities
3. Wait until the day after
4. See the incorrect behavior

Expected behavior

When the activity is related to the day before the current day, it should be shown as "yesterday".
