Revert "include authors minus releasers in contributors"

It makes the pod look goofy!

This reverts commit 9627d194830a930072a67a0f4f9d6a2b1ed5d3c3.
now require the new version that takes contributors directly from metadata
use order_by = commits (Pod::Weaver::Section::Contributors 0.008 will not re-sort)
include the bundle name in warns and dies
better diagnostic output on failure
Drop adding $AUTHORITY variables everywhere - nothing uses it, and saves us 3 lines of code offset
get all the warnings out of the way early
bring VerifyPhases back to the very end of the plugin list
Dist-Zilla-PluginBundle-Author-ETHER-0.070

          - revert git contributor change from v0.069; opened
            (github) CPAN-API/metacpan-web#1270 instead.
          - order contributors by number of commits, descending
          - no longer adding an $AUTHORITY variable to modules, as nothing
            (save Class::MOP, Moose and Moo) has ever used it - this also
            avoids shifting our line numbers by 3
