fix(ops/pipelines): limit concurrency of :llama: r/5380
When pushing a large chain of CLs, builds can fail with OOM issues as many Nix evaluations of the depot are happening simultaneously. To work around this, we limit the concurrency of simultaneous Nix evaluations (i.e. the `:llama` step). This can slow down the start of builds in a large chain of small changes, but that is a better tradeoff than failing the builds entirely and making people click buttons.
