Benjamin Wang ad4e256175 Update changelog 3.6 to clearly requiring applications which depend on etcd 3.6 packages must be built with go version >= 1.18

etcdserver starts to using generic in https://github.com/etcd-io/etcd/pull/14515,
so any applications which depend on package `go.etcd.io/etcd/server/v3' must be
built with go version >= 1.18.

Most likely we may depends on go 1.18 new features in other packages, i.e. client, pkg,
so we just simplify the changelog message to require applications depending on any
etcd 3.6 pacakges must be built with go version >= 1.18, although only etcdserver uses
go generic for now.
