docs: release notes for the v11.2.17 release

Put this right before `11.2.16` but after the latest stable and next releases so users don't think this is the latest and greatest.

Also fixed a `0.0.0` version number that leaked in. `git blame` shows that this came from https://github.com/angular/angular-cli/pull/22387, originally intended as the `10.2.4` release.
