Revert the rollback features introduced for theme and plugin upgrades during the WordPress 5.9 cycle. A bug (suspected to be in third party virtualisation software) causes the upgrades to fail consistently on some set ups. The revert is to allow contributors further time to investigate mitigation options. Reverts [52337], [52289], [52284], [51951], [52192], [51902], [51899], [51898], [51815]. Props pbiron, dlh, peterwilsoncc, galbaras, SergeyBiryukov, afragen, costdev, bronsonquick, aristath, noisysocks, desrosj, TobiasBg, hellofromTonya, francina, Boniu91. See #54543, #54166, #51857.
