devenvModules.default only added the wrapProgram-wrapped josh-sync binary,
whose bundled PATH (yq, jq, etc.) only applies while josh-sync itself runs.
Plain `yq` was never actually on PATH in a consumer's devenv shell, breaking
the manual `yq -i` config-editing commands the josh-sync skill's docs call
for. Adds pkgs.yq-go to the module's packages list directly. Bumps to v2.3.1.
