Update tutorial notebooks

[JMP-MO]

Some of the tutorial notebooks were not working due to method/class name changes in the packages which haven't been updated in the tutorial notebooks. An example of this is standard_longitude which is now StandardLongitude.

I have also made sure there is a clear explanation of how to access the local ERA5lowres data at NCI, NIWA and the Met Office with links to all 3 organisation locations in each notebook.

I have also added some additional explanation in the notebooks to try and help new users. For instance I have added context explaining how the CNN ML project works and what it is trying to predict which is then referred back to later when explaining how input / target data indexing works.

There is also an update to the IPython import in the pipeline.controller file as this import was failing with .core

@JMP-MO thanks for this. I hit a similar issue. As such I might use (and implicitly review) this PR and see if it fixes what I'm experiencing.

@JMP-MO thanks for the added descriptions its very helpful, and of course fixing the standard longitude renaming. I have some minor comments above.

I have yet to run the notebooks, but will do so soon and see if there's any regression from my end.

This all looks great to me. I added a minor bugfix which I suspect may have just been accidentally not included in the commit for some reason. I will shortly merge it, and have moved the comments into a new issue to tackle without holding up the PR.

I will merge this momentarily despite the CI failures on the pre-commit hook. I reran the black formatter to try to resolve this, and it's unclear to me why that didn't produce a compliant file. I will investigate shortly and push up a fix to the formatting separately.

Thanks Tennessee. I hope the additional explanations are useful, being brand new to the project provides an opportunity to experience what it is like getting started with the tool and I tried to explain the initial roadblocks or questions I had as I worked through the material. I might take a look at the CNN scaling code with Joel next week as I haven't seen scaling approached like that. I am guessing its to do with saving out the statistics to make the processes reversible later, whereas usually I would save the scaler object. I was saying to Stephen that developing some PET ML Pipeline Templates could be really useful for users to jump straight into ML.
