Update site URL doesn't work in recent Eclipse

[maxxyme]

The home page of your project says: https://github.com/stefaneidelloth/EclipseFolding Eclipse Update Site: https://github.com/stefaneidelloth/EclipseFolding/raw/master/com.cb.platsupp.site

However when I use this URL in my Eclipse Oxygen.3 in the "Available Software Sites" it doesn't work:

``Unable to read repository at https://github.com/stefaneidelloth/EclipseFolding/tree/master/com.cb.platsupp.site. Unable to read repository at https://github.com/stefaneidelloth/EclipseFolding/tree/master/com.cb.platsupp.site. https://github.com/stefaneidelloth/EclipseFolding/tree/master/com.cb.platsupp.site is not a valid repository location.
