the current links are wrong, they link to:

https://en.wikipedia.org/wiki/%5CPrinciple_of_least_privilege
(notice the backslash) and:
https://specs.openstack.org/openstack/%5Coslo-specs/specs/liberty/privsep.html
both links don't work this way.

you can see the broken links here:
https://opendev.org/openstack/oslo.privsep
or here:
https://github.com/openstack/oslo.privsep

from the spec:
https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#hyperlink-targets



> An external hyperlink's URI may begin on the same line as
> the explicit markup start and target name, or it may begin
> in an indented text block immediately following, with no
> intervening blank lines. If there are multiple lines in the
> link block, they are concatenated.
> Any unescaped whitespace is removed
> (whitespace is permitted to allow for line wrapping).
