Steps to Add Link on Store Configuration Fields Comment in Magento 2:

Step 1: First, create a system.xml file at the below path

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Config:etc/system_file.xsd">
    <system>
        <section id="general" translate="label" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
            <group id="my_group" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                <field id="my_field" translate="label" type="text" sortOrder="10" showInDefault="1" showInWebsite="1" showInStore="1">
                    <label>My Custom Field</label>
                    <frontend_model>Vendor\Module\Block\Adminhtml\System\Config\Link</frontend_model>
                    <comment>This is a custom field. Click <a href="https://www.magecomp.com" target="_blank">here</a> for more information.</comment>

namespace Vendor\Module\Block\Adminhtml\System\Config;

use Magento\Config\Block\System\Config\Form\Field;
use Magento\Framework\Data\Form\Element\AbstractElement;

class Link extends Field
{
    /**
     * Render the element and add a custom link to the comment field.
     *
     * @param AbstractElement $element
     * @return string
     */
    protected function _getElementHtml(AbstractElement $element)
    {
        $element->setComment(
            'This is a custom field. Click <a href="https://www.magecomp.com" target="_blank">here</a> for more information.'
