[pmg-devel] [PATCH pmg-docs v2 4/7] installation: iso: improve & align wording with pve-docs

[Christoph Heiss]

Most of the changes are taken from pve-docs to align the exact wording
in general, as well as changing a few subtle things to improve the
overall reading flow.

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