Change format of time zone information in documents created by Visualization API

[teslavitas]

Some suppliers are confused by the current format of time zone information.
In HTML generated by TED Visualization API it looks like this: 19/01/2024 14:00 +01:00 . For a person not familiar with details of time representation standards, it might be unclear whether 14:00 is a UTC time and 1 hour should be added to convert it to local time, or whether +01:00 is a time zone indicator.
eNotice2 use different format, here is an example from there: 19/01/2024 14:00 (UTC+1). This format is less ambiguous.

I suggest that TED Visualization API change format of time zone information to one used by eNotice2: (UTC+1) instead of +01:00.
