Update example-config.json

[mdole]

The CLI no longer supports skipEditorInterfaces, limit and now supports header, timeout, retryLimit, skipTags, stripTags. Update to make the example config more accurate!

Hey, hey, thanks for contributing!

This example config is meant to show all options which are available for using contentful-export as standalone tool or CLI.

With that in mind, I don't think it makes sense to adjust as you are suggesting.

I think skipEditorInterfaces and limit still will be picked up from contentful-export, see e.g. https://github.com/contentful/contentful-export/blob/master/lib/index.js#L79.

As for the new additions, I don't think all of them are supported in contentful-export directly, e.g. retryLimit is something only implemented in https://github.com/contentful/contentful-cli.

I would suggest keeping this example config to what the export tool as such supports. Let me know what you think.
