IBX-11610: Images with width="" or height="" in xml definition will cause crash

[vidarl]

🎫 Issue	IBX-11610

Description:

In 5.0, strict typing was added to width and height in ImageVariation.php. (It was not added to Image\Value.php though)

I am not able to reproduce this on a fresh 5.0 database, but if you have upgraded from older version, you might have width and/or height set to empty value ””, ie:

<?xml version="1.0" encoding="UTF-8"?>
<ezimage serial_number="1" is_valid="1" filename="300bb9aadf95-vbanner.jpg" suffix="jpg" basename="300bb9aadf95-vbanner" dirpath="var/site/storage/images/6/5/5/3/3556-1-eng-GB" url="var/site/storage/images/6/5/5/3/3556-1-eng-GB/300bb9aadf95-vbanner.jpg" original_filename="300bb9aadf95-vbanner.jpg" mime_type="image/jpeg" width="" height="" alternative_text="" alias_key="1293033771" timestamp="1775563557">
   <original attribute_id="3556" attribute_version="1" attribute_language="eng-GB" />
   <information Height="150" Width="450" IsColor="1" />
   <additional_data />
</ezimage>

If you then try to load this image in admin-ui, it wlll crash due do violation of strict typing:

An exception has been thrown during the rendering of a template ("Cannot assign string to property Ibexa\Contracts\Core\Variation\Values\ImageVariation::$width of type ?int") in "@IbexaAdminUi/themes/admin/ui/field_type/preview/content_fields.html.twig".

Seems to be the most convenient place to do this check, but is this the correct place to add it?
Alternatives are:

• in fromHash() (Don't think we ever do validation checking here ? )
• in Value\construct()
