CI: one recipe at a time on every platform (temporarily, rattler-build#2898) - #162

Conversation
rattler-build 0.77 gives two variants of a recipe started in the same second the same build directory (prefix-dev/rattler-build#2898). On the build branches beluga's two hdf5 variants are the first builds of their job, so humble's and jazzy's Linux and macOS builds fail every time. Revert once prefix-dev/rattler-build#2899 is released. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

After #112, beluga's two hdf5 variants are the first builds of their job on the build branches, so every humble and jazzy Linux and macOS build-branch run fails, including re-runs.
