fix helm template indentation for deployment.env

[shippo-eric]

This is a simple yaml typo fix. Helm template indentation for env needs to be incremented.

before:

          env:
          foo: bar

after fix:

          env:
            foo: bar

I take the liberty to update chart version, but feel free to let me know if that's not desired.

I made a mistake and realized env is a list of key/value pair, this is all good.
