Implemented the corrected significance and alpha outputs from ExcessMapEstimator using correlate_off = False (see https://github.com/gammapy/gammapy/issues/5245).
This will create artifacts in sky maps unless you are using the maps.py file in gammapy that is currently part of https://github.com/gammapy/gammapy/pull/5270. The fix should be "officially" implemented in gammapy 1.3 (coming very soon).
Additionally, some bug & docs fixes to the notebook.
