Please update the calibration_test jupyter notebook

[vmon5589]

I am using the code within a notebook you have here on github. It fails on Xe_strong input
https://github.com/jveitchmichaelis/rascal/blob/main/calibration_test.ipynb

I am using version 0.4. I installed using the second recommended route (after pip install failed):
pip install git+https://github.com/jveitchmichaelis/rascal.git

The code from your notebook that produced the error is:
c = Calibrator(peaks, elements=["Xe_strong"], min_wavelength=3400.0, max_wavelength=8100.0, range_tolerance=200)

The error produced is:

----> 1 c = Calibrator(peaks, elements=["Xe_strong"], min_wavelength=3400.0, max_wavelength=8100.0, range_tolerance=200)
2 c.set_fit_constraints(n_pix=len(spectrum))

TypeError: Calibrator.init() got an unexpected keyword argument 'elements'

In fact, most of the tutorials are incompatible with the current stable version as of this date.
For example, in the docs:
https://rascal.readthedocs.io/en/latest/tutorial/lt-sprat.html

In the line:
c.load_user_atlas(elements=element,
wavelengths=atlas,
constrain_poly=True)

The error is: "'Calibrator' object has no attribute 'load_user_atlas'"
