feat(tokens): modernize scripts and change prefix to token (#30666)

Issue number: internal

---------

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->
This pull request updates the design token build pipeline to support
Style Dictionary v5 and modernizes the scripts by migrating them to ES
modules. The changes ensure compatibility with the latest dependencies
and improve maintainability by refactoring the build scripts and
utilities.

**Dependency and Build Pipeline Updates:**

* Upgraded `outsystems-design-tokens` to version `^1.3.2` and
`style-dictionary` to version `^5.0.0` in `package.json` to support the
latest features and fixes.
* Updated the `build.tokens` npm script to use the new ES module entry
point (`index.mjs`) instead of the old CommonJS file (`index.js`).

**Migration to ES Modules:**

* Migrated the main design token build script from `index.js` to
`index.mjs`, refactoring imports/exports and adjusting to Style
Dictionary v5 API changes.

* Renamed and refactored the utility functions file from `utils.js` to
`utils.mjs`, converting all utility functions to ES module exports for
compatibility.
