Fixed improper JSON response from apis that use quote summary

[JNewman-cell]

Summary

When calling any quoteSummary-based property (such as asset_profile, earnings, financial_data, key_stats, etc.) via the yahooquery package, the returned values exhibit inconsistent response structures depending on the ticker and asset type:

For many well-known tickers (e.g. AAPL) these properties return a dictionary mapping a normalized ticker key to a nested dict with structured data (expected structure).
For many other tickers (e.g. EAI) the same properties return a dict mapping the ticker to a plain string error message, e.g. {'EAI': 'No fundamentals data found for symbol: EAI'} (unexpected structure).

This systematic inconsistency affects 15 out of 17 quoteSummary properties and causes downstream code that expects consistent dict-of-dicts structures to fail or misinterpret responses across different asset classes.
Real-world Impact

This GitHub Actions run is a real-world example of someone expecting a parsable JSON response yet receiving an unexpected response from the API.
