fix: update release scripts for react devtools (#31069)

This has been broken since the migration to GitHub actions.

Previously, we've been using `buildId` as an identifier from CircleCI.
I've decided to use a commit hash as an identifier, because I don't know
if there is a better option, and
`scripts/release/download_build_artifacts.js` allows us to download them
for a specific commit.
