Fix 500 on Knowledge Graphs/gremlin topic

[Brett Alistair Kromkamp]

See URL: https://contextualise.dev/topics/view/15/gremlin

The error is caused by including a Gremlin query in a note attached to the topic: Pygments has no support for Gremlin syntax?

The fix would be to remove the offending note.

DELETE FROM occurrence WHERE map_identifier = 15 AND identifier = '5d89c885-36a4-4103-99ae-97a7a3ca5b62';
