DocStrings are passed to step fns as instances of io.cucumber.docstring.DocString rather than java.lang.String

[danielmiladinov]

Due to how DocStrings get autowired as String instances for appropriately-annotated Java method step “functions”, the cucumber-jvm SnippetGenerator defaults to typing docString arguments as String, even though they are passed to our Clojure step functions as instances of io.cucumber.docstring.DocString – forcing users to first call

(.getContent docString)

To get the actual String value.

Burpless should be able to do this so that users don't have to.
