SNOW-2043406: Type Annotations for `snowflake.connector.connect`

[max-muoto]

What is the current behavior?

snowflake.connect lacks any type annotations, despite usage of **kwargs it's possible to share annotations between SnowflakeConnection and snowflake.connect through usage of Unpack.

What is the desired behavior?

That snowflake.connect is properly annotated making type-checkers such as MyPy and Pyright raise type-checking warnings when incorrect arguments are parsed in.

How would this improve snowflake-connector-python?

Users relying on type-checkers or Pylance would get linting errors for invalid arguments without having to execute code. Additionally, by having py.typed the package indicates it's properly typed however in this case proper annotations are missing.
