Updated Snowflake Integration Docs with Tip to Install Git

[MinuraPunchihewa]

Description

This PR adds a tip about the need to install Git in the Docker container before installing the dependencies for the Snowflake integration.

According to this comment, the official snowflake-sqlalchemy package will add support for SQLAlchemy 2 within this month. When that is done, the dependencies for the integration should be updated and this tip should be removed.

Partially fixes #9024
