Update to nodejs rules 0.31.1

[gregmagolan]

nodejs_binary entry_point is now a label. See release notes https://github.com/bazelbuild/rules_nodejs/releases/tag/0.31.0 for more info.

#455 should land first.

This commit is a pre-req to bazel-contrib/rules_nodejs#777

Need rules_nodejs snapshot builds of npm packages to fix the error here that target is using jasmine_node_test out of @bazel/jasmine:

ERROR: /workdir/internal/BUILD.bazel:115:1: //internal:test: invalid label '@bazel/jasmine/src/jasmine_runner.js' in attribute 'entry_point' in 'nodejs_test' rule: invalid repository name '@bazel/jasmine/src/jasmine_runner.js': workspace names may contain only A-Z, a-z, 0-9, '-', '_' and '.'
