add example env for easier setup, better readme

[jobenjada]

code is self-explanatory :)

[coderabbitai]

Walkthrough

Adds apps/playground/.env.example containing NEXT_PUBLIC_FORMBRICKS_API_HOST=http://localhost:3000 and NEXT_PUBLIC_FORMBRICKS_ENVIRONMENT_ID=YOUR-ENVIRONMENT-ID. Updates apps/playground/.gitignore to stop ignoring the example file (allowing !.env.example). Overhauls apps/playground/README.md: replaces "Getting Started" with "Setup", adds pnpm install, instructs creating env.local with the two Formbricks variables, uses pnpm dev to start, and documents SDK methods (setUserId, setAttribute, setAttributes, setEmail, setLanguage, track, logout). No runtime logic changes.

Pre-merge checks

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Description Check	❓ Inconclusive	The description “code is self-explanatory :)” is too vague and does not summarize any of the changes such as adding an example .env file or updating the README, so it fails to convey meaningful information about the pull request.	Please update the description to briefly explain the additions (the new .env.example file, .gitignore update, and README setup instructions).

✅ Passed checks (2 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title clearly summarizes the main changes by indicating the addition of an example environment file for easier setup and improvements to the README, which matches the core modifications in this pull request.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.

35-35: Thanks for restoring the safe ignore pattern.

.env* continues to shield real env files while the negation keeps the example tracked—exactly what we needed.
