Set column length explicitly (#11393)

... in favor of https://www.doctrine-project.org/projects/doctrine-dbal/en/3.8/reference/types.html#reference

Page: https://www.doctrine-project.org/projects/doctrine-orm/en/2.19/reference/basic-mapping.html#doctrine-mapping-types

As announced in https://github.com/doctrine/dbal/pull/6336#issuecomment-2003720361 , the goal is to remove this duplicated type information from ORM and replace it with a link to DBAL.

In https://github.com/doctrine/dbal/pull/6341 , I'm adding any detail which I'm deleting here to the DBAL.

 Doctrine Mapping Types

+The ``type`` option used in the ``@Column`` accepts any of the
+`existing Doctrine DBAL types <https://docs.doctrine-project.org/projects/doctrine-dbal/en/stable/reference/types.html#reference>`_
+or :doc:`your own custom mapping types
+<../cookbook/custom-mapping-types>`. A Doctrine type defines
 the conversion between PHP and SQL types, independent from the database vendor
-you are using. All Mapping Types that ship with Doctrine are fully portable
-between the supported database systems.
-
-As an example, the Doctrine Mapping Type ``string`` defines the
-mapping from a PHP string to a SQL VARCHAR (or VARCHAR2 etc.
-depending on the RDBMS brand). Here is a quick overview of the
-built-in mapping types:
-
--  ``string``: Type that maps a SQL VARCHAR to a PHP string.
--  ``integer``: Type that maps a SQL INT to a PHP integer.
--  ``smallint``: Type that maps a database SMALLINT to a PHP
-   integer.
--  ``bigint``: Type that maps a database BIGINT to a PHP string.
--  ``boolean``: Type that maps a SQL boolean or equivalent (TINYINT) to a PHP boolean.
--  ``decimal``: Type that maps a SQL DECIMAL to a PHP string.
--  ``date``: Type that maps a SQL DATETIME to a PHP DateTime
-   object.
--  ``time``: Type that maps a SQL TIME to a PHP DateTime object.
--  ``datetime``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object.
--  ``datetimetz``: Type that maps a SQL DATETIME/TIMESTAMP to a PHP
-   DateTime object with timezone.
--  ``text``: Type that maps a SQL CLOB to a PHP string.
--  ``object``: Type that maps a SQL CLOB to a PHP object using
-   ``serialize()`` and ``unserialize()``
--  ``array``: Type that maps a SQL CLOB to a PHP array using
-   ``serialize()`` and ``unserialize()``
--  ``simple_array``: Type that maps a SQL CLOB to a PHP array using
-   ``implode()`` and ``explode()``, with a comma as delimiter. *IMPORTANT*
-   Only use this type if you are sure that your values cannot contain a ",".
--  ``json_array``: Type that maps a SQL CLOB to a PHP array using
-   ``json_encode()`` and ``json_decode()``
--  ``float``: Type that maps a SQL Float (Double Precision) to a
-   PHP double. *IMPORTANT*: Works only with locale settings that use
-   decimal points as separator.
--  ``guid``: Type that maps a database GUID/UUID to a PHP string. Defaults to
-   varchar but uses a specific type if the platform supports it.
--  ``blob``: Type that maps a SQL BLOB to a PHP resource stream
