A few minor changes to fix a typo, broken link, and some deprecations (#322)

* Update xarray-in-45-min.ipynb - typo

* Update xarray-in-45-min.ipynb - update alias used in resample

* Update 02.2_manipulating_dimensions.ipynb - update alias used in

* Update 03.2_groupby_with_xarray.ipynb - update time alias

* Update 05_intro_to_dask.ipynb - update URL for Dask diagram
