ci: give each workflow a unique setup cache key (#5217)

Checks, publish_core_react, publish_data_grid, publish_lab and
publish_storybook all passed the bare commit SHA as the _setup.yml
cache key while checking out different sparse paths. Caches are
immutable, so when two of these workflows ran on the same push the
first save won and the others restored a workspace with the wrong
file set — on push 1243030 the Checks job restored the storybook
variant (no documentation/) and the AI component index freshness
check failed reporting every component missing.

Suffix the key per workflow, matching the pattern publish_icons
(-setup-icons) and publish_tokens (-setup-tokens) already use.

Fixes #5214
