test: see if xapian 1.4.25 will build with 3.13beta1

issue2551338 xapian doesn't build in CI for 3.13 python

Try to build xapian with newest xapian release (1.4.25 - 2024-03-07)
against the 1.4.18 libraries installed on the github CI platform.
This may work as the 1.4 ABI is supposed to be compatible.
