Bump up snowflake-connector-python version requirement to at least 2.4.0

[JustMaris]

Describe the feature

Want to install snowflake-connector-python 2.4.0+ to support PyArrow 3.0.0.

Additional context

Currently, the issue I see when I try to install a newer version is:

dbt-snowflake 0.19.1 requires snowflake-connector-python[secure-local-storage]==2.3.6, but you have snowflake-connector-python 2.4.2 which is incompatible.

Who will this benefit?

Describe alternatives you've considered
I think we can fix this by not pinning the snowflake-connector-python version to 2.3.6 specifically, but setting the version constraint to snowflake-connector-python>=2.3.6. However we should ensure that things don't break with a newer version of the snowflake-connector-python and that the test suite still pass.

Who will this benefit?
Anyone trying to install dbt-snowflake alongside the Airflow snowflake provider

This would also benefit those who would want to use Python 3.9, as support for it was added in version 2.4.0.

Are you interested in contributing this feature?

I am interested in contributing to this feature, to the extent of my almost non-existant experience and knowledge.

Hey @ClassyLion, I totally agree! As of #3148, we've already upgraded the required version of snowflake-connector-python in the develop branch:

https:/fishtown-analytics/dbt/blob/bfdf7f01b55a90ea8292e1c537b6cf44faa412ab/plugins/snowflake/setup.py#L48-L53

The next minor version of dbt (v0.20.0) will be compatible with python 3.9, PyArrow 3.0.0, and a whole bunch more.

I'm going to close this issue as a duplicate of #3170, and as something that's been resolved :)

Thank you for the response. My mistake in not finding it earlier. When will the next minor version be released?

Hoping to have an initial beta version in the next few weeks!
