Removed types list

This is really doctrine specific, the sf docs should not document this,
kind of SoC for docs 😉.

 Doctrine comes with a large number of field types available. Each of these
 maps a PHP data type to a specific column type in whatever database you're
-using. The following types are supported in Doctrine:
-
-* **Strings**
-
-  * ``string`` (used for shorter strings)
-  * ``text`` (used for larger strings)
-
-* **Numbers**
-
-  * ``integer``
-  * ``smallint``
-  * ``bigint``
-  * ``decimal``
-  * ``float``
-
-* **Dates and Times** (use a `DateTime`_ object for these fields in PHP)
-
-  * ``date``
-  * ``time``
-  * ``datetime``
-  * ``datetimetz``
-
-* **Other Types**
-
-  * ``boolean``
-  * ``object`` (serialized and stored in a ``CLOB`` field)
-  * ``array`` (serialized and stored in a ``CLOB`` field)
-  * ``blob`` (mapped to a resource stream)
-  * ``simple_array`` (serialized using :phpfunction:`implode()` and :phpfunction:`explode()`,
-    with a comma as delimiter, and stored in a ``CLOB`` field)
-  * ``json_array`` (serialized using :phpfunction:`json_encode()` and :phpfunction:`json_decode()`,
-    and stored in a ``CLOB`` field)
-  * ``guid``

-Field Options
-~~~~~~~~~~~~~
-
-Each field can have a set of options applied to it. The available options
-include ``type`` (defaults to ``string``), ``name``, ``length``, ``unique``
-and ``nullable``. Take a few examples:
-
-.. configuration-block::
-
-    .. code-block:: php-annotations
-
-        /**
-         * A string field with length 255 that cannot be null
-         * (reflecting the default values for the "type", "length"
-         * and *nullable* options)
-         *
-         * @ORM\Column()
-         */
-        protected $name;
-
-        /**
-         * A string field of length 150 that persists to an "email_address" column
-         * and has a unique index.
-         *
-         * @ORM\Column(name="email_address", unique=true, length=150)
-         */
-        protected $email;
-
-    .. code-block:: yaml
-
-        fields:
-            # A string field length 255 that cannot be null
-            # (reflecting the default values for the "length" and *nullable* options)
-            # type attribute is necessary in YAML definitions
-            name:
-                type: string
-
-            # A string field of length 150 that persists to an "email_address" column
-            # and has a unique index.
-            email:
-                type: string
-                column: email_address
-                length: 150
-                unique: true
-
-    .. code-block:: xml
-
-        <!--
-            A string field length 255 that cannot be null
-            (reflecting the default values for the "length" and *nullable* options)
-            type attribute is necessary in XML definitions
-        -->
-        <field name="name" type="string" />
-        <field name="email"
-            type="string"
-            column="email_address"
-            length="150"
-            unique="true"
-        />
