Subject: [PATCH] playground: show the grep build commit and date

The playground version line records the coreutils WASM commit and the
site commit, but grep (built as its own standalone WASM module) had no
provenance shown. Capture grep's commit/short/date in the workflow and
append a UUTILS_GREP_VERSION block to version.js, then render it next to
"Built from uutils/coreutils ..." as "grep <short> (<date>)" linking to
the uutils/grep commit.
