fixup! release: create initial Windows installer build workflow

build-git-installers: prepare for the big split of mingw-w64-git

In git-for-windows/MINGW-packages#172, the
`mingw-w64-git` package was split into multiple packages, with the
new primary package as Git for Windows is concerned being the
`mingw-w64-git-for-windows-addons` one.

Accommodate for that change by simply adding (almost) all of the packages
that were built to the command-line via `--pkg` options, instead of
hardcoding the `mingw-w64-git` and `mingw-w64-git-doc-html` one.
