Updated Docker image and Helm chart 💹

In this release, we have a few changes to the OPS side of the gem. The minor versions of all gems used in the Docker image were updated to the latest. At the same time Helm chart received the new configuration option podLabels if you want to add any labels to your exporter pod.

Hude thanks to @pauldn-wttj and @t-lo for the support with it 💙 💜
