Error loading shared library libresolv.so.2 on Alpine in Go 1.20

[bep]

I assume this is related to the changes mentioned here: https://tip.golang.org/doc/go1.20#cgo -- and that the libresolv library isn't bundled with Go anymore.

I have not found any workaround other than building with the -extldflags "-static" flag.

We currently build with:

CGO_ENABLED=1 go build -buildmode exe -tags extended

See gohugoio/hugo#10839

working as intended
