File extension is wrong from v4.23.0

[suzuki-shunsuke]

In v4.23.0, file extension was changed from .tar.gz to .tar.tgz.

I think file extension .tar.tgz is wrong, because .tgz is .tar + .gz.

This change came from #706 .

tar -czvf "/out/diun_${version#v}_${TARGETOS}_${TARGETARCH}${TARGETVARIANT}.tar.tgz" .
