Update pyproject.toml to fix issues seen in dbt-databricks

[benc-db]

pandas 2.2.0 causes several issues, notably:

TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType'

and urllib < 1.26 gives an error about Retry not having allowed_methods in its __init__

This closes #326

Rather than re-pin the dependency, we could instead write a version-contingent fix for this that checks the urllib3 version at runtime rather than locking out older users.

This can't merge until we add the new poetry.lock file as well. Instructions for this are within CONTRIBUTING.md (but I'll take care of it for you.

My only concern with this pin version is anyone using an older urllib3 than 1.26, as these were the users who voiced issues when we originally released with the version pinned to urllib3>=2.0.0.

Looking through past issues, it seems that as long as we still support urllib3==1.27.0 then the previous issues would still be avoided:

• evidence 1
• evidence 2

I also checked the default version of urllib3 in a DBSQL notebook and it's 1.26.14, so I think this change is acceptable.
