PR #41200 introduced template variables ({{ .tab }}, {{ .framework }})
to api_settings_steps.mdx for deep-linking to the Connect dialog.
However, 4 auth docs pages were calling the partial without passing
the required variables prop, causing MDX parsing errors:
- Could not parse expression with acorn: Unexpected token
This resulted in 404 errors on:
- /docs/guides/auth/server-side/creating-a-client
- /docs/guides/auth/quickstarts/nextjs
- /docs/guides/auth/quickstarts/react-native
- /docs/guides/auth/quickstarts/react
Fixes the issue by adding the variables prop to match the pattern
used in other quickstart pages.
