Breadcrumb markup for products filed in a category

[dreamwhisper]

Describe the bug
Breadcrumb markup does not always follow the Genesis markup. As a result, styling applied to breadcrumbs does not work correctly for some WooCommerce pages.

To Reproduce
Steps to reproduce the behavior:

1. Turn breadcrumbs on for Single Posts.
2. Create a category and make sure at least one product is in the category.
3. Visit the product. Note that the breadcrumb includes the category, but it is not wrapped with the breadcrumb-link-wrap span. The link also does not use the breadcrumb-link class.

Expected behavior
We need to update the Genesis Connect for WooCommerce breadcrumb output to ensure wrappers are consistent for categorized products.

Confirmed. Current source on a product page such as /product/product-name/ is:

<div class="breadcrumb" itemprop="breadcrumb" itemscope itemtype="https://schema.org/BreadcrumbList">You are here:
    <span class="breadcrumb-link-wrap" itemprop="itemListElement" itemscope itemtype="https://schema.org/ListItem">
        <a class="breadcrumb-link" href="http://dev.test/" itemprop="item">
            <span class="breadcrumb-link-text-wrap"
                  itemprop="name">Home</span>
        </a>
        <meta itemprop="position" content="1">
    </span>
    <span aria-label="breadcrumb separator">/</span>
    <a href="http://dev.test/product-category/uncategorized/" title="Uncategorized">Uncategorized</a>
    <span aria-label="breadcrumb separator">/</span>Product Name
</div>

The issues @dreamwhisper noted are both visible there:

• A separate breadcrumb-link-wrap should wrap the product category breadcrumb link.
• The product category link (“Uncategorized” in this case) should take a class of breadcrumb-link, like the Home link.

In addition:

• <meta itemprop="position" content="2"></span> is missing from the product category.
• itemprop="item" is also missing.
• The breadcrumb-link-text-wrap span is absent too.

Here's the (correct) expected output on a regular post for comparison:

<div class="breadcrumb" itemscope="" itemtype="https://schema.org/BreadcrumbList">You are here:
    <span class="breadcrumb-link-wrap" itemprop="itemListElement" itemscope="" itemtype="https://schema.org/ListItem">
        <a class="breadcrumb-link" href="http://dev.test/" itemprop="item">
            <span class="breadcrumb-link-text-wrap"
                  temprop="name">Home</span>
        </a>
        <meta itemprop="position" content="1">
    </span>
    <span aria-label="breadcrumb separator">/</span>
    <span class="breadcrumb-link-wrap" itemprop="itemListElement" itemscope="" itemtype="https://schema.org/ListItem">
        <a class="breadcrumb-link" href="http://dev.test/category/uncategorized/" itemprop="item">
            <span class="breadcrumb-link-text-wrap" itemprop="name">Uncategorized</span>
        </a>
        <meta itemprop="position" content="2"></span>
    <span aria-label="breadcrumb separator">/</span>The Secret Method to Creating the Perfect Amount of Simple

Noting that in Slack Jen pointed to gencwooc_get_single_crumb as a good place to start looking for the bug.
