sync: update sha from backports (#3079)

These files have been primarily modified by backports and need little modification:

* `topology.basic`: #1826 - modified with a porting note, which can now be removed
* `data.real.cau_seq_completion`: #1469 - not a backport, but forgot to update the SHA
* `order.filter.n_ary.basic`: #1967 - this PR forgot to update the SHA
* `ring_theory.valuation.basic`: The change is a small golf that is now included in this PR
