test(metro): Add type tests for SentryExpoConfigOptions.getDefaultConfig

[antonis]

📢 Type of change

• Bugfix
• New feature
• Enhancement
• Refactoring

📜 Description

Follow-up to #5246. Adds type compatibility tests for SentryExpoConfigOptions.getDefaultConfig as suggested in the review comment.

Two tests validate the fix:

1. New format (Expo SDK 54): A function with the flexible Record<string, unknown> signature compiles — this was the core fix, accommodating Metro type definitions that diverged between @expo/metro and the standalone metro package.

2. Old usage pattern: The classic wrapping pattern (calling expo/metro-config's getDefaultConfig and returning a spread/modified config object) still works — Record<string, unknown> options are compatible with DefaultConfigOptions (all optional fields), and the spread object return type is compatible with Record<string, unknown>.

💡 Motivation and Context

Follows up on the suggestion from @lucas-zimerman in #5246 (comment):

This is optional, but would it be possible to also include a type test to validates it's working with the new format and also the old ones?

💚 How did you test it?

• yarn test:tools — all 117 tests pass
