Trac #34110: numpy 1.23.x

(split out from #34081)

​https://numpy.org/doc/stable/release/1.23.0-notes.html# (released)

The upgrade looks harmless.

1.23.x requires GCC >= 6.5. (This has been documented in
numpy/numpy#22155 - to be included in 1.23.3.)

We set #34266 as a dependency, which increases our requirement from GCC
>= 6.3 to GCC >= 8)

Previous update:

#32423 Update numpy to 1.22.x, scipy 1.8.x, networkx 2.8.x
