Fix pnpm-lock.yaml for bench/large-app-router after React upgrade (#101642)
### What?
Fixes the `pnpm-lock.yaml` entry for `bench/large-app-router` so that
`pnpm install --frozen-lockfile` works on canary again.
### Why?
Since #101502 was merged, canary CI (`build`, `build-next`, `fetch test
timings`, `test devlow package`, …) fails at install with:
```
ERR_PNPM_LOCKFILE_MISSING_DEPENDENCY
Broken lockfile: no entry for 'lucide-react@0.554.0(react@19.3.0-canary-e84e1492-20261031)' in pnpm-lock.yaml
```
#101587 upgraded React to `19.3.0-canary-1620f7b9-20261111` while
#101502 was open. The lockfile changes merged without a textual
conflict. However, the new `bench/large-app-router` importer still
referenced the `lucide-react` snapshot that was resolved against the old
React version, and #101587 had removed that snapshot.
### How?
Point the importer at the existing
`lucide-react@0.554.0(react@19.3.0-canary-1620f7b9-20261111)` snapshot.
This is a one-line lockfile change.
### Verification
- On current canary with this change, `pnpm install --frozen-lockfile`
succeeds.
- A plain `pnpm install` leaves the lockfile unchanged ("Already up to
date").
- `pnpm-lock.yaml` has no remaining references to `e84e1492`.
