installation: zfs-options: improve & align wording with pmg-docs

These changes are the result of basically "diffing" both documentations,
choosing the better prased/sounding sections. Some wording were also
slightly changed as necessary to further improve them.

The equivalent changes will be done for pmg-docs too, to ensure they are
really the same in the end.
