⚡️ Speed up method JsonErrorMessageParser._try_get_error by 25% in PR #44010 (pnilan/airbyte-cdk-improve-error-messages-parsing)

Certainly! To optimize the given code, especially focusing on runtime improvements, we can.

1. Replace the list comprehension and generator used in the `_try_get_error` method with more efficient alternatives.
2. Optimize the dictionary look-up to check keys sequentially rather than getting values multiple times.

Here's the revised code.
