Add CI for VTop example

[GuptaManan100]

Description

When we fixed the Vtop example in Vitess last time at #10687, we also tried to run it on CI, but unfortunately, the CI didn't have enough power to run them. Since then we've gotten access to 16 cor runners, and it is now possible to run the Vtop workflow.
