The Intl component is required to use the Bic constraint

Problem/Motivation

When installing the module through composer, enabling it and adding a BIC webform element, a LogicException is raised upon displaying the webform, with the following message : The Intl component is required to use the Bic constraint. Try running "composer require symfony/intl".

Steps to reproduce

• Install module
• Enable module
• Add a BIC element to an existing/new webform

Proposed resolution

I suppose the symfony/intl package should be added to the dependencies in the composer.json of this module.
I tested it with the v7.2.0, which seems to be working.
