Missing crossreferences between hooks and guides

Hello,

We have a guide for many connection types and many hooks for these connections.

The following fragment should appear in the hook documentation:

    .. seealso::
        For more information on how to set-up connection for this hook, take a look at:
        :ref:`howto/connection:XXX`

If the class has subclasses, the note should only be in the base class.

Similar information should be found in the connection documentation.

    .. seealso::
        For more information on how to use the connection with the hook, take a look at:
        :class:`airflow`

The purpose of this change is to facilitate access to related parts of the documentation.

Best regards, Kamil

Closing as many already fixed. I’ll try to generate list for the missing ones and open a dedicated issue for them as not all providers have howto guide for connections.
