chore(linear_algebra/dimension): fix lemma names (#18747)
This fixes some lemma names which use `rank` but are about `finrank`:
* `rank_sup_add_rank_inf_eq` → `submodule.rank_sup_add_rank_inf_eq`
* `rank_add_le_rank_add_rank` → `submodule.rank_add_le_rank_add_rank`
* `submodule.rank_sup_add_rank_inf_eq` → `submodule.finrank_sup_add_finrank_inf_eq`
* `submodule.rank_add_le_rank_add_rank` → `submodule.finrank_add_le_finrank_add_finrank`
