Lets merge it once a a new released with the new feature gets released

[krystofwoldrich]

I would replace the list of the options with a section under the code snippet of the options with a description of the functionality.

For example how we do it in

sentry-docs/docs/platforms/react-native/tracing/instrumentation/react-native-navigation.mdx

Lines 27 to 54 in 5873e41

	## Options
	You can configure the instrumentation by passing an options object to the constructor:
	```javascript
	Sentry.reactNativeNavigationIntegration({
	navigation: Navigation, // Navigation from `react-native-navigation`
	routeChangeTimeoutMs: 1_000, // default: 1_000
	enableTabsInstrumentation: true, // default: false
	ignoreEmptyBackNavigationTransactions: true, // default: true
	});
	```
	### navigation
	This option is required and should be the `Navigation` object imported from the navigation library.
	### routeChangeTimeoutMs
	This option specifies how long the instrumentation will wait for the route to mount after a change has been initiated before the transaction is discarded. The default value is `1_000`.
	### enableTabsInstrumentation
	This instrumentation will create a transaction on tab change. By default, only navigation commands create transactions. The default value is `false`.
	### ignoreEmptyBackNavigationTransactions
	This ensures that transactions that are from routes that've been seen and don't have any spans, are not being sampled. This removes a lot of clutter, making it so that most back navigation transactions are now ignored. The default value is `true`.

The description already exists in https://sentry-docs-3s3vjrwvt.sentry.dev/platforms/android/configuration/gradle/ so we can just copy it.

Good idea @krystofwoldrich 👍

I would name the file gradle.mdx the same way we do in the Android docs.

[krystofwoldrich]

We should add Expo SAGP page also to the next steps on the Expo page

sentry-docs/docs/platforms/react-native/manual-setup/expo.mdx

Lines 124 to 127 in 7432e6c

	## Next Steps
	- [Learn how to upload source maps for native builds and Expo Updates](/platforms/react-native/sourcemaps/uploading/expo/)
	- [Add automatic tracing with Expo Router](/platforms/react-native/tracing/instrumentation/expo-router/)

Thank you for your feedback @krystofwoldrich 🙇
