Format the getting started section to make it clearer

[simonzhaoms]

Description

The Getting Started section in README.md is a little messy. For example:

4. Register your (conda or virtual) environment with Jupyter:

   python -m ipykernel install --user --name my_environment_name --display-name "Python (reco)"

5. Start the Jupyter notebook server

   jupyter notebook

will look better than:

4. Register your (conda or virtual) environment with Jupyter:

python -m ipykernel install --user --name my_environment_name --display-name "Python (reco)"

5. Start the Jupyter notebook server

jupyter notebook

Please compare getting started@simonz/format-getting-started with getting started@staging
