This PR removes opendatahub.io/dashboard: 'true' label from rstudio ImageSteams

[jiridanek]

I was wondering why the annotation was not present in https://github.com/opendatahub-io/notebooks to begin with.

Apparently notebook-related annotations are not present in that repo at all

• Add a notebook specific label opendatahub-io/notebooks#387

edit: when I say annotation I mean label
