add ldflags back

Summary

I've run a v0.10.0-rc.1 and when checking the output of the version command some information were missing

$ ./rekor-cli-darwin-arm64 version
  ____    _____   _  __   ___    ____             ____   _       ___

rekor-cli: Rekor CLI

GitVersion:    v0.10.0-rc.1
GitCommit:     unknown
GitTreeState:  unknown
BuildDate:     unknown
GoVersion:     go1.18.4
Compiler:      gc

which sounds weird because if build locally I can see it

$ ./dist/rekor-cli-darwin-arm64 version
  ____    _____   _  __   ___    ____             ____   _       ___

 |  _ <  | |___  | . \  | |_| | |  _ <  |_____| | |___  | |___   | |
 |_| \_\ |_____| |_|\_\  \___/  |_| \_\          \____| |_____| |___|

maybe the is related to the proxy that we use? not sure.
but to make sure we have the data we need I'm adding back the ldflags
