services: guix-publish: Add zstd compression by default.
That way, the default config with (advertises? #t) and without a cache will offer zstd-compressed substitutes, which should lead to much higher throughput than gzip. * gnu/services/base.scm (default-compression): When 'guix-publish-configuration-cache' returns true, use higher level compression ratios. Add "zstd". * doc/guix.texi (Base Services): Mention zstd.
