Point banner link to YOLO Vision 2026 registration

[raimbekovm]

The YOLO Vision 2026 "Register now" banner (image swapped in ultralytics/assets#184) is embedded here, but the click still went to the Platform or a generic link. This repoints only the banner's link to the YOLO Vision 2026 event page so the clickable banner matches its call to action.

Only the link wrapping the banner-yolov8 image is changed; all other links are untouched. Banner image is unchanged (swapped in-place via the assets repo).

Deleted: nothing — one-line link corrections; the previous URLs are replaced, nothing to relocate or remove.
