[bug#42477] [PATCH] gnu: newsboat: Update to 2.20.1.

[Efraim Flashner]

* gnu/packages/syndication.scm (newsboat): Update to 2.20.1.
[source]: Add snippet to loosen version requirement on crate dependency.
[build-system]: Switch to cargo-build-system.
[native-inputs]: Remove asciidoc, add openssl, asciidoctor.
[arguments]: Add gnu-build-system module. Add vendor-dir, cargo-inputs,
cargo-development-inputs fields. Don't delete 'configure phase. Add
custom 'dont-vendor-self-phase. Replace 'build, 'check, 'install phases
with gnu counterparts.
(newsboat-2.13): New variable.
---

This is the patch from when I recorded some of my package updating on
Guix. I'm sending it to guix-patches instead of just pushing it because
I wanted to make sure I did the right thing with the variable names.
