🔧 chore(document): replace ESLint with Biome

[acasazza]

Summary

Replace ESLint and all related plugins in the packages/document package with Biome, aligning with the rest of the monorepo (packages/react-components already uses Biome).

Changes

• Remove eslint, @eslint/js, typescript-eslint, eslint-plugin-react-hooks, eslint-plugin-react-refresh, eslint-plugin-storybook, globals devDependencies
• Remove eslint.config.js
• Remove eslintConfig field from package.json
• Update lint script to biome lint ./src

Motivation

Consistent tooling across the monorepo. Root biome.json already covers all packages.
