[Community] Renaming Nexus Operator Package (remove)

[ricardozanini]

I'm renaming the Nexus Operator package to not clash with the certified one. Please, only merge this one if the counter part (#1707) will be merged as well.

Thanks submitting your Operator. Please check below list before you create your Pull Request.
