Subject: [PATCH] CI: don't cancel package builds across the matrix on one
 failure

The package-arch and package-indep matrices use the default
fail-fast behavior, so a failure in one matrix job cancels all
others. When debian:sid is temporarily uninstallable (e.g. the
adios2 2.11 -> 2.12 transition currently breaking the
python3-opencv dependency chain), the bookworm and trixie package
builds are cancelled too and the whole matrix turns red.

Set fail-fast: false so each distribution builds independently and
only the genuinely broken job fails.
