Approve dependencies in pnpm and pin pnpm version in Gradle (#2482)

Fixes failure in #2481. The pnpm version was unpinned, so it quietly moved to pnpm 11, which introduced several breaking changes including one with approved builds (specifically, strictDepBuilds). Since we're on pnpm 11 anyways, use their new system for approving postinstalls for certain dependencies.
