Fix contextutils test registerreceiver overload mismatch

[romtsn]

📜 Description

Updated ContextUtilsTest to correctly verify Context.registerReceiver calls for API 32-.

💡 Motivation and Context

The ContextUtilsTest for API 32- was incorrectly verifying a 4-parameter overload of context.registerReceiver. In Android, the 4-parameter registerReceiver method internally delegates to the 5-parameter overload, passing 0 as the default flags value. This fix updates the test to verify the 5-parameter overload with flags = 0, accurately reflecting the runtime behavior and aligning with how other tests verify registerReceiver calls.

💚 How did you test it?

The updated test itself verifies the fix by asserting the correct Context.registerReceiver overload and parameters are called.

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
