Checkout NLog Wiki and generate nlog-project.org/wiki

[snakefoot]

Could be neat if build-step was added to NLog.github.io, so it would produce indexable Wiki:

• https://nlog-project.org/wiki/
• https://github.com/NLog/NLog.wiki.git

Pull-requests are wellcome

Taking a shot at this one.
It creates a GH Action that can be triggered manually currently. It will build as /wiki and it will try to commit the built items to the master branch. Therefore the github actions token needs WRITE permission (GitHub Repo Settings -> Actions -> General -> "Read and write permissions" under "Workflow permissions")

There is already a repository_dispatch trigger, which can possibly be fired using this github action from the main repository whenever the WIKI is updated to re-generate the website wiki:
https://github.com/marketplace/actions/repository-dispatch

Let me know, and I'll try to also make a PR for that in the main repo
