Fix DataFrame.info() range summary for DatetimeIndex

**Fix `DataFrame.info()` range summary for DatetimeIndex** This PR aims to provide better description of [DatetimeIndex](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DatetimeIndex.html) within [DataFrame.info](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.info.html) in relation to the display of the range of unsorted indexes, by replacing the original first to last element values with "min date" to "max date" values.
