Publish 32-bit and arm64 clients (#1009)

Adjustment to our goreleaser configuration so that we publish the
 - 32-bit Windows client
 - 32-bit Linux client
 - 64-bit Arm64 client

That means we now publish 6 clients; the above along with:
 - 64-bit Windows
 - 64-bit Linux
 - 64-bit Darwin

I don't think the other combinations of goos/goarch make sense to publish.

Fixes #1005
