Converts notebook plots to pure Plotly

[BradyPlanden]

Description

This PR removes the svg based plotting methods for jupyter notebooks, changing to standard to the plotly.show() method. As this remove the rendered figures in GitHub, I've added a README.md to the examples directory which points users to the nbviewer rendered notebooks, which is the recommend method for plotly.

As a result of the above, this PR removes kaleido as a dependency.

Hi Brady! I am not sure I follow what this PR changes (mostly because I am not too familiar with plotly). It seems the main change is to use a log scale in the plots, but there are still some issues with the exponents (see https://github.com/pybop-team/PyBOP/blob/7bae73c60da37932851f8373cc567f8f35e8a078/examples/notebooks/multi_model_identification.ipynb)

[BradyPlanden]

I've now refactored this PR quite a bit, after hitting a few blockers with Kaleido and the GitHub notebook renderer, I've changed direction and reverted notebook plotting to the standard plotly.show() implementation. This reduces the maintenance quite a bit and is much more robust. The only drawback is that the notebook figures won't be rendered on Github. To solve this, a README has been added directing users to the nbviewer implementation.

Hi @BradyPlanden, when I try to view the figures on nbviewer (e.g. 1-single-pulse-circuit-model), it only shows me one figure and the rest are black rectangles. I am using Firefox on Windows, same on Chrome. Will this issue be fixed by merging?

[BradyPlanden]

Yes it will be fixed by merging, here's the link to this branch which has the fixed plots: https://nbviewer.org/github/pybop-team/PyBOP/blob/410-bug-incorrect-axis-symbol-rendering-formu-in-notebooks/examples/notebooks/equivalent_circuit_identification.ipynb

Looks good to me, thanks!
