[incubator/monochart] Dockercfg name mismatch

[RothAndrew]

Environment

Chart: incubator/monochart v0.25.0

What I expect

If I use the following in values.yaml

dockercfg:
  enabled: true
  image:
    pullSecret:
      registry: foo
      username: bar
      password: baz
...

A secret is created and referenced correctly in a Deployment's pullSecrets

What I experienced

If, for example, my release name is foo, the secret is named foo-dockercfg but the imagePullSecrets section in the deployment says

imagePullSecrets:
  - name: foo-monochart

Since they don't match, the image pull fails.

I got it to work with this, but it obviously isn't ideal
