Fix incorrect ordering in api-docs-nav-data.json (#21404)

https://github.com/hashicorp/vault/pull/20595/files#diff-9c9c146a6465b0deafac528d60a94bee5f609ac37c203005bd3b5cda6c190882 was a contrib which added a new endpoint, however the ref to the page in api-docs-nav-data.json was incorrectly added and thus appears out of order in the left sidebar, i.e. https://developer.hashicorp.com/vault/api-docs/system/decode-token

website/data/api-docs-nav-data.json
