Add "name" field to package.json to Resolve Webpack chunk loading conflicts

[PierreMigani]

Subject

Hello,

I'd like to suggest a small change to the project, that might avoid issues for users also using webpack for asset management.

Issue Description

I'm a contributor to a Symfony project that uses Sonata for our admin interface.
In our project, when updating our outdated sonata-project/form-extensions Composer package, we encountered a conflict between our webpack runtime and the sonata-project/form-extensions runtime.

This conflict happens because both try to use the same global JavaScript variable, globalThis.webpackChunk, to load chunks. The name of this variable is defined by the Webpack option output.chunkLoadingGlobal.
webpack option reference: https://webpack.js.org/configuration/output/#outputchunkloadingglobal

This issue made our chunks load twice, causing our JavaScript to run twice, which led to unexpected problems.

Research and Temporary Solution

When we looked into the problem, we found out that webpack 5 solves it by automatically giving unique names to its global variables with the output.uniqueName option, which per default uses the name field from package.json.
webpack option reference: https://webpack.js.org/configuration/output/#outputuniquename

However, we noticed that our package.json did not define the name field, and neither did the package.json from sonata-project/form-extensions. To temporarily resolve this issue, we added a name to our package.json, which successfully mitigated the conflict.

Feature Request

To prevent similar conflicts in the future with webpack-managed projects, I suggest adding a name field to the package.json. This change would help ensure that webpack generates a unique name for all its globals.

Changelog

### Added
- `name` field to `package.json`, avoiding webpack globals conflicts issues with other webpack projects
