Provide changelog for @apollo/explorer package?

[viddo]

It appears the linked repository URL https://github.com/apollographql/embeddable-explorer yields contained in the npm package yields a 404 not found. I recall that the explorer was available in some other repository, but maybe it was moved again or made private, could you confirm?

I did find https://www.apollographql.com/blog/why-isnt-apollo-explorer-open-source after writing the above, so I guess that might explain it. That said, given https://www.npmjs.com/package/@apollo/explorer is public, could you include a CHANGELOG.md or something equivalent in the package, so one can know what changed and how to go about potential breakages?

Thanks!
