[EXTERNAL] Removes some duplicate files

[EXTERNAL]

I noticed in groupie-tracker (but also in other subjects) that there are duplicate files inside the project's directories. Apparently, there is this pattern:

subjects/<project>/<subproject>/{audit.md,audit/README.md}

The only think changing between them is the link to the good-practices document.

Why?

They seem to serve no purpose. As far as other projects' structures suggest, the README.md file under the audit directory of a subproject is the one that is valid.

Solution Overview

Removal of the duplicates for the groupie-tracker's subprojects.

Implementation Details

In the cases included in the PR, I choose to remove only the ones for groupie-tracker project.

I choose to not remove other duplicates, since there are some cases that the differences exceed the link to the good-practices document. For example, in the subproject 0-shell/job-control, one suggests to run ls while the other suggests tar. While the convention seem to be straight-forward, for those that differ more than the link, I wanted to check with you first and I can append the current PR or revisit on a new one.

I found those with the following:

find . -type f | grep audit.md | while read line; do echo $line | cut -d '/' -f 3,4; echo "==================="; diff $line ${line/.md//README.md}; echo; done
