docs(data-lab): unify Virtuoso image across main and shadow store 

The 6G-DALI baseline ran the shadow store on 7.2.8 (Ubuntu) against 7.2.14-alpine
on the main store — drift, not a requirement. Both instances speak the same
SPARQL Graph Store protocol, so one pinned image is enough and halves the patch
surface. Kept at 7.2.14 rather than the current 7.2.17, since 7.2.14 is what
assumption E3 leans on as proven against piveau-hub-repo 3.3.11.
