Improved UX of creating TimestampNanosecondArray with timezones

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
While working on apache/datafusion#4039 and https://github.com/influxdata/influxdb_iox/pull/6061 I ended up having to do this many times:

Arc::new(TimestampNanosecondArray::from(vec![...],)
  .with_timezone("+0:00".into())

While this API is already nicer than previously, there are two more improvements that might help:

Describe the solution you'd like
Allow passing &str as well as String to with_timezone:

Arc::new(TimestampNanosecondArray::from(vec![...],)
  .with_timezone("+0:00")

Add an alias for UTC:

Arc::new(TimestampNanosecondArray::from(vec![...],)
  .with_timezone_utc()

Describe alternatives you've considered

Additional context

I think this is a good first issue as the code and tests are already there, all that is needed is a signature change (from String to impl Into<String>) and some tests

i'll take it if there's no one take it this week or next.
if there's anyone interested in, i happy to point out the codes to modify

@waitingkuo I can help with this. Which file(s) should I modify?

@src255
you could add the with_timezone_utc() here
https://github.com/apache/arrow-rs/blob/master/arrow-array/src/array/primitive_array.rs#L762-L797

and follow this to add a test case
