Try using UpgradeData instead of UpgradeSchema.

Your UpgradeData.php looks like:

<?php
namespace Lime\Merchant\Setup;

use Magento\Framework\Setup\UpgradeDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Catalog\Api\ProductRepositoryInterface;

class UpgradeData implements UpgradeDataInterface
{
    /**
     * @var \Magento\Catalog\Model\ProductFactory
     */
    private $productFactory;

    /**
     * @var ProductRepositoryInterface
     */
    private $productRepository;

    /**
     * UpgradeData constructor.
     *
     * @param \Magento\Catalog\Model\ProductFactory $productFactory
     * @param ProductRepositoryInterface $productRepository
     */
    public function __construct(
        \Magento\Catalog\Model\ProductFactory $productFactory,
        ProductRepositoryInterface $productRepository
    ) {
        $this->productFactory = $productFactory;
        $this->productRepository = $productRepository;
    }

    public function upgrade(
        ModuleDataSetupInterface $setup,
        ModuleContextInterface $context
    ) {
        $setup->startSetup();
        if ($context->getVersion() && version_compare($context->getVersion(), '1.0.1') < 0 ) {
            $this->createVirtualProduct();
        }

        $setup->endSetup();
    }

    public function createVirtualProduct()
    {
        /** @var \Magento\Catalog\Model\Product $product */
        $product = $this->productFactory->create();
        $product->setName('E-Book');
        $product->setTypeId('virtual');
        $product->setAttributeSetId(4);
        $product->setSku('ebook');
        $product->setWebsiteIds(array(1));
        $product->setVisibility(4);
        $product->setPrice(1000);
        $product->setStockData(array(
                'use_config_manage_stock' => 0, //'Use config settings' checkbox
                'manage_stock' => 0, //manage stock
                'is_in_stock' => 1, //Stock Availability
                'qty' => 100000, //qty
                'tax_class_id' => 0
            )
        );

        $this->productRepository->save($product);
    }
}
