Show absolute date/time on notes instead of relative

[gjvoosten]

Previously, notes in the side-panel would show a relative date/time such as "4 hours ago". Now, the date/time is shown as absolute (formatted as defined in the dictionary by the dateFormats.forms.displayShort.withTime key), e.g. "23 March 2021 @ 09:34".

Closes #3501
