Quote values for ingress annotations as discussed in #483 (#497)
Quote all values for Ingress annotations as discussed in https://gitea.com/gitea/helm-chart/issues/483
Annotations are currently not quoted, and can not be set to non-string values using the _--set_ with _helm_ (see examples in issue).
Annotations for ingress-nginx MUST be quoted: https://github.com/kubernetes/ingress-nginx/blob/main/docs/user-guide/nginx-configuration/annotations.md#annotations
```
!!! tip Annotation keys and values can only be strings. Other types, such as boolean or numeric values must be quoted, i.e. "true", "false", "100".
