Update CoC adapted from upstream 2.1 (instead of 1.4)

[zimoun]

Hi,

The current Guix CoC is adapted from v1.4 [1] and this upstream version
contains:

        regardless of age, body size, disability, ethnicity, sex
        characteristics, gender identity and expression, level of
        experience, education, socio-economic status, nationality,
        personal appearance, race, religion, or sexual identity and
        orientation.

and for some unclear reasons the term ’sex characteristics’ is not in
commit a076f19908d06b6df49f1c25c40de8838213cd71.  No reference in the
thread [2] mentioned by the commit message; or I missed it.  2018 is too
old to use my broken memory. :-)

Any opposition to use this upstream v1.4 list instead of the current
one?  Other said, add ’sex characteristics’ to the list.


So, since we are at it, let give a look at the most recent version v2.1
[3]. :-) I propose to adopt their extended list:

        regardless of age, body size, visible or invisible disability,
        ethnicity, sex characteristics, gender identity and expression,
        level of experience, education, socio-economic status,
        nationality, personal appearance, race, caste, color, religion,
        or sexual identity and orientation.

Any opposition?

The version 2.1 also adds «Enforcement guidelines».  I propose to keep
the current «Further details of specific enforcement policies may be
posted separately.»  While the guidelines might be a good thing.  I do
not have an opinion.  WDYT?

Last, if we update the CoC, do not forget the typo [4].
