Addresses review comments from: * https://review.opendev.org/#/c/638269/63/doc/source/admin/configuration/resize.rst * https://review.opendev.org/#/c/696212/6/doc/source/admin/configuration/cross-cell-resize.rst Also updates contributor/resize-and-cold-migrate since that is relatively new and biased toward same-cell resize and cold migrate. However, I chose to link the same-cell resize glossary term to that contributor doc rather than admin/configuration/resize because the admin doc is woefully bare.
