zizmor flags every write to GITHUB_ENV, and the pipeline-cache action had one
purely to hand the cache directory to the step that follows it. The value is a
constant, so the step can carry it directly. Each pipeline invocation now sets
PNPM_CONFIG_CACHE_DIR itself, and the action documents the path it reads.
