Prefer Pickle.Location with fallback to Lineage

[davidjgoss]

🤔 What's changed?

Pickle.Location is present in newer versions of Cucumber, so if it's there we should use it rather than go through the Lineage to get it. We should still maintain the fallback though, since Query will be used for formatters that might still be dealing with messages from older versions.

(This brings the .NET and JavaScript versions in line with what Java was already doing.)
