[ADAP-1043] Handle errors more gracefully when Snowflake is configured to use languages other than English

[nathaniel-may]

New issue for problem raised in #834 with associated Community PR .

Snowflake allows users to set their language. When we string match to catch errors on the English wording this fails to catch errors when Snowflake is configured to use a language other than English.

• What was the original reason the code uses string matching here?
• Is there an alternative, language-agnostic way for us to identify errors? (python class types, error codes etc)

Definition of Done:
When a user configures Snowflake to use any language other than English, the error handling behavior remains the same.
