#1123 added a warning when the OpenGL version is too old, but
it is never used because GTK enforces the version set with
gl_area.setRequiredVersion() before prepareContext() is called:
we end up with a generic "failed to make GL context" error:
warning(gtk_ghostty_surface): failed to make GL context current: Unable to create a GL context
warning(gtk_ghostty_surface): this error is almost always due to a library, driver, or GTK issue
warning(gtk_ghostty_surface): this is a common cause of this issue: https://ghostty.org/docs/help/gtk-opengl-context
This patch removes the requirement at the GTK level and lets the ghostty
renderer check, now failing as follow:
info(opengl): loaded OpenGL 4.2
error(opengl): OpenGL version is too old. Ghostty requires OpenGL 4.3
warning(gtk_ghostty_surface): failed to initialize surface err=error.OpenGLOutdated
warning(gtk_ghostty_surface): surface failed to initialize err=error.SurfaceError
(Note that this does not render a ghostty window, unlike the previous
error which rendered the "Unable to acquire an OpenGL context for
rendering." view, so while the error itself is easier to understand it
might be harder to view)
