Color changing and incorrect orientation of buttons

We do not want the stock information of the products available in the carousel to be displayed on the home page.
Is there a solution to this without installing a plugin?
It should be displayed on the product detail page but not in the carousel.

We don’t want the text “in stock” in the image, but we want it to be on the product page.

add_filter( 'woocommerce_get_availability', 'wcs_custom_get_availability', 1, 2);
function wcs_custom_get_availability( $availability, $_product ) {
   // Change In Stock Text
   if ( $_product->is_in_stock() ) {
     $availability['availability'] = __('Available!', 'woocommerce');
   }
   // Change Out of Stock Text
   if ( ! $_product->is_in_stock() ) {
     $availability['availability'] = __('Sold Out', 'woocommerce');
   }
   return $availability;
}

They changed the out of stock text with this code
How can we do this for backorder?
and where do we add this code?

There is no change with the language files, we saved the code below as a snippet with wpcode and the problem was solved.

add_filter( 'woocommerce_get_availability_text', 'filter_product_availability_text', 10, 2 );
function filter_product_availability_text( $availability_text, $product ) {
    if ($product->get_stock_status() === 'onbackorder') {
        $availability_text = __( 'Sipariş verdiğinizde tedarik edilir' );
    }
    return $availability_text;
}
