[ADDED] CI: Add loong64 to release

[znley]

I need nats-server release to build container image for loong64. https://hub.docker.com/u/loongarch64\
GoReleaser has officially supported loong64 architecture. goreleaser/goreleaser#3277

Note that this will build a loong64 artefact, but will not automatically result in a linux/loong64 OCI container image — that part is handled elsewhere. Is it specifically a container image that you're looking for?

Yes, the OCI container image will be handled on docker hub and loong64 artifact is required to build the image.

LGTM

The first loong64 builds are present in v2.11.7-RC.1: https://github.com/nats-io/nats-server/releases/tag/v2.11.7-RC.1

The Docker image has also been updated to reference the artefact: https://github.com/nats-io/nats-docker/blob/367cd93883e036965df424eb1eb2bf7697afb6c5/2.11.x/alpine3.22/Dockerfile#L15

... but because there's no alpine:3.22 base image for linux/loong64 present on Docker Hub, we cannot currently automate their builds.

Yes, docker hub does not support loongarch64 yet for their own reasons. But releasing the binary is a very important step, which means I can fork their pipeline to build container image.
