Several parameter descriptions were carried over from unrelated variables and
described the wrong attribute. Both country name parameters claimed to document
a Common Name, the client organizational unit name repeated the Common Name text
and the two client content parameters described a passphrase and a key
algorithm.
The client content parameters now follow the wording already used for their root
and intermediate counterparts. The README tables were regenerated with
readme-generator, which also normalises the column padding of the previously
hand-edited rows.
Additionally fix the misspelled repository owner in the homepage URL and a typo
in the galaxy description.
