Fix Python Voyage AI error handling to use SDK exception types

- Remove accidentally added .python-version file
- Update get_embedding() to catch specific voyageai.error exceptions:
  - AuthenticationError (401) -> VoyageAuthError
  - InvalidRequestError (400) -> VoyageAPIError
  - RateLimitError (429) -> VoyageAPIError
  - ServiceUnavailableError (503) -> VoyageAPIError
  - VoyageError (other) -> VoyageAPIError
- Import VoyageAuthError and VoyageAPIError in tests for future use

This fixes the issue where authentication errors were not being properly
detected because the code was relying on string matching instead of
catching the SDK's specific exception types.
