AlgebraicGeometry.isLocallyNoetherian_of_affine_cover

∀ {X : AlgebraicGeometry.Scheme} {ι : Sort u_1} {S : ι → ↑X.affineOpens},
  ⨆ i, ↑(S i) = ⊤ →
    (∀ (i : ι), IsNoetherianRing ↑(X.presheaf.obj (Opposite.op ↑(S i)))) → AlgebraicGeometry.IsLocallyNoetherian X

If a scheme X has a cover by affine opens whose sections are Noetherian rings, then X is locally Noetherian.
