tools: enable eslint concurrency mode

[JLHwung]

In this PR we enable the ESLint --concurrency mode. Per report from TIME(1), a cache-missed eslint job has improved from 75 seconds to 25 seconds on my machine. In the cache-hit scenario, both mode exit in less than 2 seconds.

We also bumped all eslint deps. Linter is still happy, no code changes are required.
