Documentation proof reading

• The instructions in the Lasair readthedocs don't match the architecture of the directory

FUTURE HELOISE: hoooo I get it, API_examples is a stand-in for API_ztf and API_lsst.

wasn't clear to me with the formatting, maybe just use the actual directory names in the repo?

Also should change the cloning instructons to
git clone git@github.com:lsst-uk/lasair-examples.git
