Docs: Typo in docstring example

[juleswg23]

The docstring example for initiating the Connect API client has a typo.

connectapi/R/connect.R

Lines 5 to 12 in c05ab8f

	#' @section Usage:
	#' \preformatted{
	#' client <- Connect$new(server = 'connect.example.com',
	#' apiKey = 'mysecretkey')
	#' client$get_apps()
	#' client$get_tags()
	#' }
	#'

apiKey should be api_key
