[PATCH 9/9] index.rst: move release notes in their own section

The release notes are currently hidden in the welcome page, under the
"Release Manuals" section, but these changelogs/migration guides are not
release manuals per say. Move them out of the "Release Manuals" section
under their own "Release Information" section, and make them appear as a
"Release Notes and Migration Guides" section in the welcome page.
