OpenAPI for server-server API is not published

[richvdh]

The OpenAPI specs for most of the APIs are available at https://spec.matrix.org/{version}/{api}/api.json. Examples:

• https://spec.matrix.org/latest/client-server-api/api.json
• https://spec.matrix.org/v1.7/application-service-api/api.json
• https://spec.matrix.org/latest/push-gateway-api/api.json

However, the server-server api is not there. Previously, this was due to invalid data (#14), but that is now fixed. We should update

matrix-spec/.github/workflows/main.yml
