Just modify the menu file located under /vendor/magento/module-cms/etc/adminthml/menu.xml

<add id="Magento_Backend::mgs" title="Blocks" translate="title" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::mgs" action="cms/block" resource="Magento_Cms::block"/>

Here's how it'll look

<?xml version="1.0"?>

-->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Backend:etc/menu.xsd">
    <menu>
        <add id="Magento_Cms::cms_page" title="Pages" translate="title" module="Magento_Cms" sortOrder="0" parent="Magento_Backend::content_elements" action="cms/page" resource="Magento_Cms::page"/>
        <add id="Magento_Cms::cms_block" title="Blocks" translate="title" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::content_elements" action="cms/block" resource="Magento_Cms::block"/>
        <add id="Magento_Backend::mgs" title="Blocks" translate="title" module="Magento_Cms" sortOrder="30" parent="Magento_Backend::mgs" action="cms/block" resource="Magento_Cms::block"/>
    </menu>
</config>
