Ability to adjust Nginx ConfigMap

We need to be able to adjust the Nginx ConfigMap. For example, in order to update the https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/configmap/#annotation-value-word-blocklist

It would be awesome if the ConfigMap is exposed like it is in the Helm Chart, https://github.com/kubernetes/ingress-nginx/blob/a9c9a9d51e48f50edd5e8e3084a5c485366ba6c4/charts/ingress-nginx/values.yaml#L52

Start by reviewing the operator's handling of the Nginx deployment and comparing the requested setting with the referenced Helm values.yaml entry. Confirm how the ConfigMap is currently created or exposed, then verify that users can configure the annotation-value-word-blocklist setting through the operator as they can through the Helm chart.
