build: Use libadwaita 1.6.beta for accent colors
Trying to compile xdg-desktop-portal-gnome 47.beta with libadwaita 1.5.3 results in errors like:
../src/settings.c: In function ‘get_accent_color’:
../src/settings.c:150:3: error: unknown type name ‘AdwAccentColor’
150 | AdwAccentColor color;
| ^~~~~~~~~~~~~~
../src/settings.c:156:15: error: ‘ADW_ACCENT_COLOR_BLUE’ undeclared (first use in this function); did you mean ‘G_DESKTOP_ACCENT_COLOR_BLUE’?
156 | color = ADW_ACCENT_COLOR_BLUE;
| ^~~~~~~~~~~~~~~~~~~~~
| G_DESKTOP_ACCENT_COLOR_BLUE
I think we only need libadwaita 1.6.alpha, but since there is a subproject wrap file, I figured we might as well use 1.6.beta instead. (I don't know whether it even makes sense to have a libadwaita subproject since most of GNOME 47 Beta needs a build of libadwaita 1.6).
