MalformedJsonExceptionin serenity.conf line# 18

[StephenDillon]

Hello,

Running on windows with serenity-gradle-plugin:2.3.5 and serenityCoreVersion=2.3.5

Running this example I am getting Could not instantiate class org.openqa.selenium.chrome.ChromeDriver.
Took a little digging but it looks like the error is related to the below line not being valid json

download: "{prompt_for_download: false,directory_upgrade: true,default_directory:'${user.dir}/downloaded-files'}"

Caused by:
com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Invalid escape sequence at line 1 column 76 path $.
