chore: drop the dead allowBuilds entry for the git-SHA comfy-multi-player

The entry existed to approve the git dependency's `prepare: npm run build`.
A registry tarball ships prebuilt `dist` and pnpm does not run `prepare` for
it, so the entry now approves a build that cannot happen — while leaving the
last `git+ssh://git@github.com/...#6793d754` string in the repo outside the
lockfile, which is precisely the stale reference the switch was meant to
remove. Verified `pnpm install --frozen-lockfile` still installs the package
with no build-approval prompt.
