add mcli/mc from pgsty/mc to Docker image

Rework Dockerfile.goreleaser to download the latest mcli binary from
pgsty/mc GitHub releases, verify its SHA-256 checksum, and install both
mcli and mc (symlink) into the final image alongside minio and curl.
Also add download-static-curl.sh to goreleaser extra_files and enable
workflow_dispatch for the release workflow.
