fix(tokens): use dynamic import for prettier in writeJson

[GarthDB]

Fixes ERR_MODULE_NOT_FOUND: Cannot find package 'prettier' when @adobe/spectrum-tokens is used outside the monorepo (e.g. via npx @adobe/spectrum-design-data-mcp).

• Removes top-level import { format } from "prettier" from packages/tokens/index.js
• Uses dynamic await import("prettier") inside writeJson so the module loads without prettier installed
• MCP and other consumers that only use getTokensByFile / getAllTokens no longer fail on load
