    docs: Specify the minimum version of GL provided by the core profile
    
    When using GDK_GL_PROFILE_3_2_CORE, we are not only specifying that the
    GDK should create a core profile; we are also specifying that the
    minimum required version of OpenGL is set to 3.2.
    
    We should also specify that the GDK_GL_PROFILE_DEFAULT profile is an
    alias for GDK_GL_PROFILE_3_2_CORE.
