2. Fill out the following pre-review checklist:

   • I am adding a new automated test(s) to verify correctness of my new code
     • If this test skips Local Testing mode, I'm requesting review from @snowflakedb/local-testing
   • I am adding new logging messages
   • I am adding a new telemetry message
   • I am adding new credentials
   • I am adding a new dependency
   • If this is a new feature/behavior, I'm adding the Local Testing parity changes.
   • I acknowledge that I have ensured my changes to be thread-safe. Follow the link for more information: Thread-safe Developer Guidelines

3. Please describe how your code solves the related issue.

Add logic to the no-op AST testing code to create a temp read-only table for to_snowpark_pandas. This way to_snowpark_pandas works with both nop mode and local_testing_mode.

nit: maybe add a simple unit/integ test for this?

[sfc-gh-vbudati]

I don't think that's necessary/it would be redundant since the to_snowpark_pandas.test test will fail if there's something wrong with this generation
