feat: configurable annotations for gitea StatefulSet (#315)

Fixes #314

Right now, the gitea StatefulSet does not allow any annotations to be configured via the helmchart - see https://gitea.com/gitea/helm-chart/src/tag/v5.0.4/templates/gitea/statefulset.yaml#L4-L6

My use case:

I am trying to use Reloader (https://github.com/stakater/Reloader) so that I can configure my values.yaml such that i can set some annotations on the StatefulSet and thus Reloader can rollout a restart of gitea StatefulSet whenever a watched secret or configmap is updated.
