Always specify kube args in kubectl commands in helmfile (#4344)

## Motivation

If running multiple deploys in parallel, you could accidentally run
these kubectl commands in the wrong context.

## Proposal

Ensure that all kubectl commands have the proper args specified

## Test Plan

Deployed a network with this, works as expected.

## Release Plan

- Nothing to do / These changes follow the usual release cycle.
