Issue # 767 Display Local Time Zones for Revisions in Search Results and Selected Revisions

[hibaa03]

This pull request implements the following changes close #767 :

Display Local Time Zones: Added functionality to display the local time zone alongside each revision timestamp. It shows me time in my local timezone (GMT+5) as in the screenshot below. Used the day.js library witth timezone plugin to accurately retrieve and format timezone abbreviations based on the local time.

UTC Timestamp Tooltip: Introduced a tooltip that shows the UTC timestamp when hovering over the local time.

Time Zone in Selected Revision: Ensured the local time zone is also displayed for any selected revision, along with the UTC on hover through a tooltip.

Compactness: Displayed time and time zone in a more digestible format. Highlighted key information (time and time zone) with bold styling

Great effort, Hiba, however, the design requires a more compact version of the timezones. See below.

Your version also breaks the style for my time zone:
