## Summary
Fix the `cms-webiny` example so non-preview requests read
`NEXT_PUBLIC_WEBINY_API_URL`, matching the README, deploy button, and
`.env.local.example`. The previous `NEXT_PUBLIC_WEBINY_API_UR` typo
caused the default API endpoint to resolve to `undefined`.
## Verification
- `rg -n
"NEXT_PUBLIC_WEBINY_API_UR|NEXT_PUBLIC_WEBINY_API_URL|NEXT_PUBLIC_WEBINY_PREVIEW_API_URL"
examples/cms-webiny`
- `git diff --check`
- Not run: full example runtime (`cms-webiny` requires external Webiny
API credentials)

## Description
This PR ensures that the default prettier config is used for examples
and templates.
This config is compatible with `prettier@3` as well (upgrading prettier
is bigger change that can be a future PR).
## Changes
- Updated `.prettierrc.json` in root with `"trailingComma": "es5"` (will
be needed upgrading to prettier@3)
- Added `examples/.prettierrc.json` with default config (this will
change every example)
- Added `packages/create-next-app/templates/.prettierrc.json` with
default config (this will change every template)
