_No response_

### Description

Running the optional migration after skipping the build migration during initial update incorrectly installs @angular/build v20 which is not compatible

### Minimal Reproduction

https://github.com/simhnna/angular-build-migration-demo/tree/8971afceeaf60bbe9fff4c9a2777b7711dcb095f

Run `ng update @angular/cli --name=use-application-builder`

```
The installed Angular CLI version is outdated.
Installing a temporary Angular CLI versioned 20.1.0 to perform the update.
Using package manager: npm
Collecting installed dependencies...
Found 22 dependencies.
** Executing 'use-application-builder' of package '@angular/cli' **

❯ Migrate application projects to the new build system.
Application projects that are using the '@angular-devkit/build-angular' package's 'browser' and/or 'browser-esbuild' builders will be migrated to use the new 'application' builder.
You can read more about this, including known issues and limitations, here: https://angular.dev/tools/cli/build-system-migration
The output location of the browser build has been updated from "dist/project" to "dist/project/browser". You might need to adjust your deployment pipeline or, as an alternative, set outputPath.browser to "" in order to maintain the previous functionality.
UPDATE package.json (1032 bytes)
UPDATE angular.json (2749 bytes)
✔ Packages installed successfully.
Migration completed (2 files modified).
```

It installs [`@angular/build@20`](https://github.com/simhnna/angular-build-migration-demo/blob/main/package.json#L26) because it uses @angular/cli@20 to run the update

リンクされた再現手順を使用して、`ng update @angular/cli --name=use-application-builder` で呼び出される `use-application-builder` マイグレーションから始めます。`package.json` と `angular.json` の変更、および一時的な CLI が `@angular/build` をどのように解決するかを調査します。マイグレーションによって更新対象のプロジェクトと互換性のあるバージョンがインストールされ、このバージョン選択のケースをカバーするテストがあることが完了の条件です。
