Serve the Release/schedule.json file from the website

Right now, my package nodevu relies on Release/schedule.json to enrich Node.js version data. This information - even if inaccurate or unreliable! - is very helpful at enriching dist/index.json into a more end-user friendly API.

I'd really love it if this information was available on the website directly, even if put in an experimental/untrusted/unreliable position (/dist/DONOTUSE/schedule.json, /untrustworthy/schedule.json, etc.). In talking with @ovflowd, apparently nodejs.org's usage of nodevu does sometimes get rate limited by GitHub because it's hitting this file frequently enough.

I recall that in the past @nodejs/release has been hesitant to provide a contract for this file. I'd be 100% okay with taking on the maintenance burden of having breaking changes be unannounced and fully reliant on consumers with no commitment from @nodejs/release. Having it on the website would just be really nice.

Start by tracing how the website serves dist/index.json and review the source Release/schedule.json, including the proposed URL options in the issue. Done means the schedule data is available from the website at an agreed path, with its experimental or unreliable status made clear to consumers.
