Update Niklas Gögge's entry in data.json (#15)

* Update Niklas Gögge's entry in data.json

@tearful-saw Fixed! Line 513 is now perfectly aligned at 4 spaces to match sibling entries (like line 529). Inner fields remain at 6 spaces. All verified data regarding Gögge's authorship and Brink mentorship is intact. Ready for merge.

* fix: close sources array on Niklas Gögge entry

Adds the missing ] that was preventing data.json from parsing.
