Update date_histogram docs (#56922) (#57387)
* Make it more clear that you can use `month` or `1M`.
* Explain rounding rules
* Consistently use "time zone" instead of "timezone". It looks like both
  are right but I see "time zone" much more. And the parameter in
  elasticsearch is `time_zone` so we may as well line up.

Closes #56760
