Publish help text for the configuration options on website

[murchandamus]

I just rediscovered Is there really no manual for Bitcoin Core? on Stack Exchange, and I must admit that finding the documentation of the configuration options can be a bit difficult. I propose that we publish the configuration help in a similar manner as the RPC documentation as the only online sources I know of are the debian man pages (which seem to be from version v0.21.0), and Lopp’s configuration editor.

Especially for novices, it might not be obvious to start your binary with the -help flag, or what to do when your operating system doesn’t come with man pages.
