chore: Remove /lore redirect from deployment template

[szewaiyuen6]

Description

A follow-up PR to: #8492

Removing the outdated /lore redirect (replaced by /gen redirect in the previous pr). It was kept around as GenAI CI wasn't caught up.

Test Plan

(1) Tested that the cluster can be launched with the change

(2) tested that the master.yaml indeed contains the update (only /genai redirect is seen)

(3) tested that /genai redirect still works

Commentary (optional)
