New Route Request: Reuters Fact Check section

### Category

Social Media

### Website URL

https://www.reuters.com/fact-check/

### What content should be included?

Each RSS item should include:

Title of the fact-check article
Link to the full article
Publication date
A short description/summary (the article's dek or opening paragraph)
Featured image, if available
Author name, if available

This would follow the same format as the existing /reuters/:category/:topic? route output.

### Additional description

It would be great if the Fact Check section could use the same approach (section alias fact-check), rather than scraping the rendered HTML directly, since direct requests to https://www.reuters.com/fact-check/ currently return blocked/empty responses for non-browser clients.

Happy to help test once a draft route is available.

### This is not a duplicated rss request

- [x] I have searched [existing issues](https://github.com/DIYgod/RSSHub/issues) and [pull requests](https://github.com/DIYgod/RSSHub/pulls) to ensure this rss proposal has not already been requested

Start by locating the existing /reuters/:category/:topic? route and compare its output with the Reuters Fact Check section at https://www.reuters.com/fact-check/. Add a fact-check section alias using the same route format, including the requested article fields and avoiding direct rendered-HTML scraping; done means the draft route produces the expected RSS items and can be tested successfully.
