Strip fourth version segment when downloading JQ binaries

[Copilot]

The publish workflow fails when the release tag contains four segments (e.g., v1.8.1.1) because it attempts to download jq-1.8.1.1 from jqlang/jq, which only publishes three-segment versions.

Changes

Modified the download step to normalize version tags before downloading:

# Extract and normalize version: v1.8.1.1 → 1.8.1
JQ_VERSION="${JQVERSION##*/}"
JQ_VERSION="${JQ_VERSION#v}"
JQ_VERSION=$(echo "$JQ_VERSION" | sed -E 's/^([0-9]+\.[0-9]+\.[0-9]+)\.[0-9]+$/\1/')

This strips the fourth segment when present while preserving two- and three-segment versions unchanged (e.g., v1.7 → 1.7, v1.8.1 → 1.8.1).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/jqlang/jq/releases
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>If the release tag has four segments, ja download fails</issue_title>
<issue_description>The publish.yml workflow downloads the JQ binaries matching the version tag. But since we sometimes also ship nuget versions with an additional fourth revision number for C#-only updates, we need to fix the workflow to ignore that when downloading JQ.</issue_description>
