refactor(algebra/geom_sum): remove definition (#14120) There's no need to have a separate definition geom_sum := ∑ i in range n, x ^ i. Instead it's better to just write the lemmas about the sum itself: that way simp lemmas fire "in the wild", without needing to rewrite expression in terms of geom_sum manually.
