[libadwaita] Release 1.0.0-alpha.1

[Adrien Plazas <aplazas src gnome org>]

commit faa9f26a2b8a89923c0b83d42e84078f672c19ec
Author: Adrien Plazas <kekun plazas laposte net>
Date:   Thu May 27 12:44:27 2021 +0200

    Release 1.0.0-alpha.1
    
    Use SemVer as our versioning scheme, and release libadwaita
    1.0.0-alpha.1 as the first alpha version of the libadwaita 1 API. The
    first beta will be 1.0.0-beta.1 and the first stable will be 1.0.0.
    
    Given the library was unreleased and pre-alpha, this version number
    change isn't regarded as a break but as a fix, and applications using
    the library and checking its version number are held responsible for
    updating their code.
    
    Fixes https://gitlab.gnome.org/GNOME/libadwaita/-/issues/44
