[lexical-playground] Bug Fix: Build dev playground in development mode#8565

Conversation
`vite build` defaults to `--mode production`, so the `build-dev` script (used by `build-vercel` to deploy playground.lexical.dev) was actually producing a production build: terser-minified, with Lexical invariant messages replaced by "Minified Lexical error #NNN" codes and __DEV__ warnings stripped. This made the public playground's tracebacks unreadable despite being intended as the non-minified dev environment. Pass `--mode development` so the playground resolves the development builds of the Lexical packages and keeps full error messages, and set `minify: false` for non-production builds (Vite's default minifier is esbuild, which would otherwise still minify the output). https://claude.ai/code/session_011e3NgM9ZdKcW6YQ9yR3TmZ

Description
I'm pretty sure we had playground building in dev a while ago, which made debugging and issue reports easier. This restores that.
