Correcting the struct according to the response from the API

The existing documentation is failing to get the published date with the current format of struct. Here is the error seen while printing the date.

.\news-test.go:94:42: result.DatePublished undefined (type struct { Name string "json: \"name\""; URL string "json: \"url\""; Image struct { Thumbnail struct { ContentUrl string "json: \"thumbnail\""; Width int "json: \"width\""; Height int "json: \"height\"" } "json: \"thumbnail\""; Description string "json: \"description\""; Provider []struct { Type string "json: \"_type\""; Name string "json: \"name\"" } "json: \"provider\""; DatePublished string "json: \"datePublished\"" } "json: \"image\"" } has no field or method DatePublished)
