Add workflow to publish OpenAPI schema to NapCatDocs

Introduces a new 'publish-schema' job in the auto-release workflow. This job builds the napcat-schema package, copies the generated OpenAPI schema to the NapCatDocs repository under a versioned path, and commits the update. Automates schema publishing on release events.
