docs: redirect /guide/ivy to the v12 guide (#46820)

gkalpak · thePunderWoman · commit df87f4afb5ce · 2022-07-13T21:59:18.000Z
Since Ivy is the default since v13, the Ivy guide (that used to live at https://angular.io/guide/ivy) has been removed (see #43860). However, there are certain error messages emitted by the CLI that still point to it. This commit address the problem by adding a redirect from https://angular.io/guide/ivy to https://v12.angular.io/guide/ivy (which is the last version that includes the guide). Fixes #46717 PR Close #46820
