Use latest versions for packages in colab tutorials

[NelsonG-C]

Description

The package versions were fixed to a specific version in the colab notebooks. This was giving users an import error due to recent version changes. I have removed the fixed version so that it now uses the latest version of each package.

I have run a fresh notebook in colab for basic_loading_and_analysing.ipynb with the change and there is no longer an import error.
