chore(bazel): bump rules_js to address permissions denied warning (#63419)

Previously we were having soft-warnings around permissions in badly made
npm packages
```
(21:31:30) WARNING: Remote Cache: /mnt/ephemeral/output/__main__/execroot/__main__/bazel-out/k8-fastbuild/bin/node_modules/.aspect_rules_js/[email protected]_react_18.1.0/node_modules/its-fine/src/index.tsx (Permission denied)
```
When trying to enable compact execution log, this becomes a hard fail
```
(14:44:58) ERROR: /mnt/ephemeral/workdir/sourcegraph/sourcegraph/BUILD.bazel:33:22: Extracting npm package [email protected]_react_18.1.0 failed: IOException while logging spawn: /mnt/ephemeral/output/__main__/execroot/__main__/bazel-out/k8-fastbuild/bin/node_modules/.aspect_rules_js/[email protected]_react_18.1.0/node_modules/its-fine/dist/index.cjs (Permission denied)
```
This bump should fix that

## Test plan

CI still builds successfully
