feat: use relative and absolute dates in email

[BKM14]

Closes #15322

Used formatToHumanReadableDate to show absolute dates, rather than only relative dates. When the date is clicked, it flips between relative and absolute. The click on the date, doesn't show or hide the email body. Attaching a recording of the same below.
