Someone here posted info on raising a slab at reasonable cost a few
weeks ago. Apparently a hole is drilled and limestone injected until
the slab is level. If you slab is not level that might be the correct
fix. It was relatively cheap according to the post and worked well.

Why not just cut the garage door to fit the angle? I've seen that done on
This Old House.
