Create a Helm Chart for our bots` secrets

[jpopelka]

The first part of our bot/service deployment is deploying/updating secrets.

Create a Helm Chart for it.

Do some research around best practices regarding Helm and secrets and/or check some existing charts to see how others do it:

• https://gitlab.cee.redhat.com/osci/osci-helm-charts
• https://github.com/helm/charts/tree/master/stable (example)

and/or see how we've done it so far:

• https://github.com/packit/helm/blob/main/helm-charts/packit-service-validation/values.yaml#L27
• https://github.com/packit/helm/blob/main/helm-charts/packit-service-validation/templates/secret-github.yaml
• https://github.com/packit/helm/blob/main/values/packit-service-validation/Makefile#L4
