Update snowflake-setup.md (#5204)

Add link to specific Snowflake docs section that determines whether
region and cloud platform need to be included.

## What are you changing in this pull request and why?
<!---
Customers are often unsure of whether or not they need to include the
region and cloud platform in the account field when connecting to
Snowflake. While we do touch on the region aspect in our doc, the
inclusion (or exclusion) of the cloud platform is less clear. The link
to this specific section of the Snowflake documentation takes the
customer directly to where they can find this information.

-For AWS accounts in the US West default region, you can use `abc123` (without any other segments). For some AWS accounts you will have to append the region and/or cloud platform. For example, `abc123.eu-west-1` or `abc123.eu-west-2.aws`. For GCP and Azure-based accounts, you have to append the region and cloud platform, such as `gcp` or `azure`, respectively. For example, `abc123.us-central1.gcp`. For details, see Snowflake's documentation: "[Specifying Region Information in Your Account Hostname](https://docs.snowflake.com/en/user-guide/intro-regions.html#specifying-region-information-in-your-account-hostname)". Please also note that the Snowflake account name should only be the <account_name> without the prefixed <organization_name>.
