Remove npm-asset/ace-builds from require and remove asset-packagist.org from repositories

Problem/Motivation

http://asset-packagist.org Issues and too slow
We could save time on each build when removed and use an alternative method.
For sure we could have faster CI/CD jobs too.

Reasons to consider alternatives:

• Project Activity: Asset-packagist is not very actively maintained. If you notice outages or slow updates, this may become a risk.
• Modern Standards: The PHP and frontend community is moving towards direct usage of npm/yarn for managing JavaScript/CSS assets, separating PHP dependencies (Composer) and JS (npm/yarn).
• Security: Relying on third-party mirrors for asset delivery can introduce risks if the service is compromised or discontinued.
• Official Recommendations: Yii2 and newer frameworks now generally recommend using npm/yarn/Webpack/Vite etc. for asset management.

Alternatives to asset-packagist:

• Direct NPM/Yarn: Use npm/yarn for JavaScript and CSS dependencies. Manage frontend assets separately from PHP dependencies.
• Composer Asset Plugin: This was previously used but is also not actively maintained and can have performance issues.
• Custom build scripts: Integrate asset bundling (Webpack, Vite, etc.) into your deployment/build process, copying built assets into your PHP project.

---

In my opinion a project can manage JS/CSS or CKEditor libraries by (NPM, yarn) in (webpack, vite)
