Fix VSCode extension build: regenerate package-lock.json (#2617)

## Summary

- Snyk PR #2305 bumped `diff` from 8.0.2 to 8.0.3 in
`js/VSC-Extension/package.json` without regenerating the lockfile
- This causes `npm ci` to fail with a "package.json and
package-lock.json are in sync" error
- Ran `npm install` to regenerate `package-lock.json` (resolves `diff`
to 8.0.4, the latest matching `^8.0.3`)

## Test plan

- [x] Verified `npm ci` succeeds with the updated lockfile
- [x] Diff is minimal: only the `diff` package version change (4
insertions, 4 deletions)
