testsuite.yml - fix and rename "authors" CI workflow to "authors_involved_debug"

The existing name is confusing to me, especially when the workflow gets
skipped so change the name to something more intuitive.

We also change it to respect .mailmap by using %aN and %aE instead of
%an and %ae.

We also change it to use ".." and "..." in the git log statement, and
use `sort | uniq -c` instead of `sort -u`, it is helpful to see counts.
We also show the resolved begin and end commits.
