Increase Helm chart version per each deployment

[utr1903]

Description

Currently, each Docker image is created with a new tag. However a new Helm deployment does not deploy the newer Docker image since the chart version always remains the same.

Expected Behavior

Each new Helm chart deployment should deploy the newest version of the application without the need to delete the instances.

Additional context

Solution proposal 1: Use proper Helm release workflow and host the Helm charts within the repo -> hard way.
Solution proposal 2: Add an additional kubectl step in advance to Helm deployment which deletes all the necessary pods -> easy way.
