[RNMobile] Fix List block's e2e test

[fluiddot]

gutenberg-mobile PR: wordpress-mobile/gutenberg-mobile#3014

Description

Native e2e tests use the title prop of toolbar buttons as the ID for querying them in Appium, in a recent PR the value of Convert to ordered list button was changed and so the test is failing because it can't find the element.

Appium error:

Error: [elementByAccessibilityId("Convert to ordered list")] Error response status: 7, 
NoSuchElement - An element could not be located on the page using the given search parameters.

Since the value changed the fix has only implied to update the value.

How has this been tested?

This PR can be tested by running the List block's native e2e test for each platform:

1. Run: cd packages/react-native-editor
2. For Android run: npm run test:e2e:android:local gutenberg-editor-lists-@canary
3. For iOS run: npm run test:e2e:ios:local gutenberg-editor-lists-@canary

For more information about running e2e tests, check UI tests instructions (aka e2e tests).
