[NuGet.org Bug]: Sponsor link emits invalid HTML

[kzu]

Impact

I'm unable to use NuGet.org

Describe the bug

See https://www.nuget.org/packages/ThisAssembly.Constants (view source).

The HTML for the Sponsor link div container is:

<div class="external-link-container">
    <i class="ms-Icon ms-Icon--Link sidebar-link-icon" aria-hidden="true"></i>
    <a href="https://github.com/sponsors/devlooped" target="_blank" rel="nofollow noopener noreferrer" class="sidebar-link" data-sponsorship-url=""https://github.com/sponsors/devlooped"">
        https://github.com/sponsors/devlooped
    </a>
</div>

notice the (invalid) extra quotes around the sponsorship URL

Repro Steps

Navigate to the page, do View Source, and find the data-sponsorship-url element. You may need to curl the page to get the broken HTML

Expected Behavior

HTML is actually valid.
