Idiot proofing the how to build the Libadwaita variant on README

[nesper8]

For context I am someone who has little to no experience with programming let alone go so it kinda made me dumbfounded when i tried to make the libadwaita variant by running go install -tags libadwaita which didnt work obviously

then i tried passing the tags flag on to the quick build command which shown this error

go install github.com/diamondburned/gtkcord4@latest -tags libadwaita 
go: -tags: all arguments must refer to packages in the same module at the same version (@latest)

so it would be cool if you could idiot proof the README a bit more Thank you very much in advance

go install -tags libadwaita github.com/diamondburned/gtkcord4@latest should work. In the future, the libadwaita build might become the default build, so no tags would be needed then.

Thank you very much I'll close the issue now

I'm getting this error when i tried to build with the command above

# pkg-config --cflags  -- libadwaita-1
Package libadwaita-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libadwaita-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libadwaita-1' found
pkg-config: exit status 1

Verbose output:

github.com/diamondburned/gotk4-adwaita/pkg/adw
# pkg-config --cflags  -- libadwaita-1
Package libadwaita-1 was not found in the pkg-config search path.

Closing I'm an idiot

When I'm an idiot in the future, install libadwaita-1-dev if I get that error
