mingw-w64-asciidoctor: install to sdk

[dennisameling]

In a recent change, GfW switched from the homegrown -asciidoctor-extensions package to the MSYS2-provided -asciidoctor one, as there's no need for the former nowadays.

The changes from #18 don't actually do much in this specific SDK, because unlike git-sdk-64 and git-sdk-32, -asciidoctor-extensions was never installed on git-sdk-arm64 in the first place.

This commit installs -asciidoctor and its dependencies:

mingw-w64-clang-aarch64-gdbm-1.19-3
mingw-w64-clang-aarch64-libyaml-0.2.5-2
mingw-w64-clang-aarch64-pdcurses-4.4.0-1
mingw-w64-clang-aarch64-ruby-3.1.5-1
mingw-w64-clang-aarch64-asciidoctor-2.0.23-1

I'd prefer to have this as a patch to update-via-pacman.ps1, so that it is more obvious that a boring old workflow installed the packages, not a human being (which would have security implications).

So maybe you can change this conditional clause to trigger on the absence of var/lib/pacman/local/mingw-w64-*-asciidoctor-[0-9]* instead of the presence of the corresponding -asciidoctor-extensions folder?

That should have the same effect as this here PR, but easier to reason about how safe the change is.

Works for me! Will update the script in the next 1-2 days as I wrap up some other work.

Might make sense to split it into one part that removes mingw-w64-asciidoctor-extensions if installed and one part that installs mingw-w64-asciidoctor if missing.
