build(ci): bump artifact actions to clear Node 20 warning

upload-artifact v4.6.2 -> v7.0.1 (clears Node 20 deprecation warning),
download-artifact v4.3.0 -> v8.0.1 (pairs with upload v7).

clojure-lint-action left on its working master-pinned SHA; the v1 tag's
Dockerfile (node:10-slim) no longer builds. The SHA is the real pin.
