[PATCH] doc: clarify distinction between sign-off and pgp-signing

[cornelius.weig@tngtech.com]

From: Cornelius Weig <cornelius.weig@tngtech.com>

The documentation for submission discourages pgp-signing, but demands
a proper sign-off by contributors. However, when skimming the headings,
the wording of the section for sign-off could mistakenly be understood
as concerning pgp-signing. Thus, new contributors could oversee the
necessary sign-off.

This commit improves the wording such that the section about sign-off
cannot be misunderstood as pgp-signing. In addition, the paragraph about
pgp-signing is changed such that it avoids the impression that
pgp-signing could be relevant at later stages of the submission.

Notes:
    This patch summarizes the suggested changes.
    
    As I don't know what is appropriate, I took the liberty to add everybody's
    sign-off who was involved in the discussion in alphabetic order.
