As per SAP VORA troubleshooting page:
Download: SAP customers can download the software on the SAP Support Portal
Spark Controller: Installations and Upgrades -> A-Z -> H -> SAP HANA PLATFORM EDITION -> SAP HANA PLATFORM EDIT. 1.0 -> Entry by Component -> HANA SPARK Controller
SAP HANA VORA 1 (SUPPORT PACKAGES AND PATCHES)
But I do not see any Spark Controller download in SAP download page. Is the download location changed for Spark Controller.
Your screenshot shows the Vora Downloads (under 'V'). The Spark Controller is part of HANA. You need to follow the path that you pasted in your question - under 'H' (Installations and Upgrades -> A-Z -> H -> SAP HANA PLATFORM EDITION -> SAP HANA PLATFORM EDIT. 1.0 -> Entry by Component -> HANA SPARK Controller).
