fix: etcd import paths again depend on v3.4.14 release (#11020)

Due to botched upstream renames of project repositories
and incomplete migration to go.mod support, our current
dependency version of `go.mod` had bugs i.e it was
using commits from master branch which didn't have
the required fixes present in release-3.4 branches

which leads to some rare bugs

https://github.com/etcd-io/etcd/pull/11477 provides
a workaround for now and we should migrate to this.

release-3.5 eventually claims to fix all of this
properly until then we cannot use /v3 import right now
