This was merged but haven't been propagated to https://github.com/asyncapi/spec/blob/master/.github/workflows/if-nodejs-release.yml and https://github.com/asyncapi/spec-json-schemas/blob/master/.github/workflows/if-nodejs-release.yml properly. Any advice?

• for https://github.com/asyncapi/spec it did not as if-nodejs-release.yml is actually a legacy file that should not be there. Spec is its own beast, with dedicated release workflow. Updates for if-nodejs-release.yml and other node related workflow no longer go there as nodejs topic is not there on the repo. And in general, there is nothing node-related with this repo
• for https://github.com/asyncapi/spec-json-schemas I actually see all is good, and change was propagated properly https://github.com/asyncapi/spec-json-schemas/pull/256/files

Right, so I'll issue last PR that merges master to next-spec branch on asyncapi/spec repo and we should be fine there as well.
