BLD: Update minimum Python in meson.build to 3.12

   PR summary

   The minimum Python was raised to 3.12 in #31740, but the version check on find_program in meson.build still says '>= 3.11'. pyproject.toml asks to keep the two in sync ("Also keep in sync with find_program of meson.build").

   When building through meson-python, find_program returns the build interpreter (the "python" entry of meson-python's native file), so this check is what rejects an unsupported Python at meson setup. On Python 3.11 it now stops with "found 3.11.x but need: '>= 3.12'" instead of passing the check.

   The CI failures look unrelated to me.

   Docs failure has been seen before. AppVeyor timed out. Codecov due to missing build.

   Approving and merging.
