This issue is automatically created based on existing pull request: #38179: Remove the "required" UI setting because it is not being used

---

This pull request removes the required UI setting because it is not being used.

The required node within the settings node was introduced in Magento 2.2.0 5affd8a#diff-8aee8246d682b388c846bcfd4c2b9191c18af2fa9fea845324805421d62b579f
It purposes was to define whether the rendered field is required. However, this functionality already covered by the validation setting. The required-entry rule node within the validation node determines whether the field is required or not.
For example,

<field name="name" sortOrder="10" formElement="input">
    <settings>
        <validation>
            <rule name="required-entry" xsi:type="boolean">true</rule>
        </validation>
    </settings>
</field>

We can refer to the initObservable and _setClasses functions in the Magento_Ui/js/form/element/abstract JS component located in the vendor/magento/module-ui/view/base/web/js/form/element/abstract.js file.

Since the required node within the settings node is not being used, it should be removed from the Magento codebase.
