Following the standardization of the table headers' formatting in 746b8305, a slight deviation was reintroduced in 5984314a.
This commit re-normalizes the headers so they're consistent again.

According to the spec: https://spec.openapis.org/oas/v3.1.0#server-variable-object

This should validate a `description` field, not `descriptions`.

* Update schema.yaml
