   Fixes SNOW-1871355

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.

Having COMPATIBLE_WITH_MODIN defined in utils.py causes conftest to fail some stored procedure Snowfort tests when the version of snowpark-python imported by the stored procedure is older than the version of the tests being run (the tests files are cloned directly from GitHub and seem to pull the latest version, whereas some stored procedures are run in older python versions and have older versions of snowpark-python). Moving the definition of COMPATIBLE_WITH_MODIN into conftest avoids this issue and maintains backwards compatibility.

The failure is because COMPATIBLE_WITH_MODIN is not defined in snowflake/snowpark/_internal/utils.py for version 1.25.0 which is what the stored proc is running, since it is on python 3.8, and that's the latest version of snowpark-python available for 3.8.

Change makes sense. Better than the original code anyways because that variable is test only anyways.
