Regex to append extension to file path

I'm trying to get running a GitHub action link checker that checks markdown files for URLs. I have a Jekyll site.

The link checker looks for files, rather than full URLs, as a result:

This fails - /docs/article1/

But this works - /docs/article1.md

I have the following rewrite in place that works for most use cases:

{    "pattern": "(\\S+)\/(\\s|$)",    "replacement": "$1$2"  }  

However, it does not work if the trailing slash is missing from the the link.

Can someone recommend a regex update that will capture either:

• /docs/article1/
• /docs/article1

And rewrite it as /docs/article1.md?
