[litmus] Fresh install of litmus 3.0.0 fails on upgrade-agent

[wrdls]

After implementing workarounds for #339 and #340 I hit the following issue:

litmus-upgrade-agent-cp-1-v7sqs upgrade-agent 2023-10-09T13:58:26.707181972+02:00 {"level":"fatal","ts":1696852706.706867,"caller":"upgrade-agent/main.go:54","msg":"failed to create upgrade manager","error":"failed to get previous version data from db, error=mongo: no documents in result","stacktrace":"main.main\n\t/upgrade-agent/main.go:54\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:225"}

Hey @wrdls Thanks for pointing this out, We are removing upgrade-job from the templates for now to remove any confusion, as we are not supporting DB upgrade from 2.x.x to 3.x.x - #342

It will be added again once we support DB upgrade for upcoming versions!

I also had to remove the upgrade-job for getting this working. I am using mongo-atlas.
