Missing link to the data file

Hi,

I notice that there is a missing link to downloading the DAOD file here in section "Set up the AnalysisBase environment"

One source I found that is likely the same file is here: /eos/user/g/gstark/public/DAOD_EXOT27.17882744._000026.pool.root.1 but it's not listed anywhere in this particular tutorial, which should be the latest version endorsed by ATLAS.

In another note is that there are various versions of dangling tutorials on the internet from different years and workshops. They are all maintained to a different degree. It would likely be super useful for future users if they can all have a url that point to this latest tutorial.

Thanks for making and maintaining the tutorial. :)
