ci(freebsd): make numpy install non-fatal

py312-numpy isn't published in FreeBSD 14.1's pkg repository yet, so
pkg install fails the job before the build even starts. The ML SUITE
already self-skips when numpy isn't importable, so the right move is
to log a warning and move on rather than block CI on an upstream
package gap.
