Fix translation script

[wendy-aw]

• Previously, schema names could still be found in the instructions of sqlite, mysql, bigquery. Script will now scrub these.
• Fixed ddl_to_dialect which had redundant preprocessing that was accidentally removing some column descriptions.
• Preserved new lines in translated ddl with the arg pretty=True
• Removed schema names from cot_instructions if one of the 3 dialects above.
• Also changed model for translation to gpt-4-turbo. Hopefully it can correct the date arithmetic translations in Date arithmetic errors, ILIKE in instructions #172
• Minor: took the chance to modify a print statement in run_checkpoints_adapters

Thanks for the fixes Wendy! Just checking if this also fixes the "schema present in cot_instructions" problem?

Ahh yesss my bad I forgot about that. That's still there. Working on it now!

Awesome, thank you! Feel free to just tag me here once you make a push and we can then merge it :D

I also made a tiny change to the cot prompt!
