DOC: Correct some wording mistakes in xarray documentation (#11120)

* an Pandas -> a Pandas

Fix comment formatting in get_duck_array method.

* an 1d -> a 1d

* A a mapping -> A mapping

* Cast a arrays -> Cast arrays

* a added dimension -> an added dimension

* a all dimensions -> all dimensions

* a attribute -> an attribute
