LinkedIN URL sharing looks not great

[dimwetoth]

Describe the bug
The OpenSearchCon North America 2024 page when shared on LinkedIN by URL produces a blank graphic box

To Reproduce
Steps to reproduce the behavior:

1. Go to opensearch.org
2. Click on 'OpenSearchCon in the top-nav
3. Click on OpenSearchCon 2024 North America
4. share the URL to the OpenSearchCon North America home page
5. Watch as it brings up a huge blank picture box when you share the URL

Expected behavior
A picture in place of a blank image, or an opensearch logo, or no picture at all. This is a very shareable page and there should be a share image associated with it.

• Browsers: Chrome

Additional context
This is likely a site-wide problem and we should perhaps be pursuing something that works as a default share image if one doesn't exist.

@dimwetoth - Thank you for the callout on this. I was just encountering the same issue.

I have to agree with this. We need to set up our twittercard and site sharing metadata. I'll prioritize this and add it to our upcoming issues to work on.
