JavaScript-based traversal using /_api/traversal

The long-deprecated JavaScript-based traversal functionality has been removed in v3.12.0, including the REST API endpoint /_api/traversal.

The functionality provided by this API was deprecated and unmaintained since v3.4.0. JavaScript-based traversals have been replaced with AQL traversals in v2.8.0. Additionally, the JavaScript-based traversal REST API could not handle larger amounts of data and was thus very limited.

Users of the /_api/traversal REST API should use AQL traversal queries instead.
