**Description**

It would be nice to be able to specify resources for the `git-sync` sidecar in the helm chart values.

**Use case / motivation**

I don't want to use keda for autoscaling and would like to setup a HPA myself. However this is currently not possible since it is not possible to specify resources for the `git-sync` sidecar.

**Are you willing to submit a PR?**

Yes, I am willing to submit a PR.
