`zed` is obviously dead and not maintained anymore
(https://zef.me/how-to-abandon-open-source-d5ebbc6e45e5).
As the last upstream commit was in 2015 we faced and will face many
issues with its dependencies due to the outdated upstream which can be
fatal when having security issues in the NodeJS ecosystem to fix.
One example is the handling of `nwjs` which is currently version `0.23`,
but `zed` relies on `0.9`. In order to reduce the maintenance overload
because of dead packages it's better to get rid of `zed` entirely.
