Thank you for the PR @valtlai!

While I do agree that \d is better than [0-9], I don't think that replacing 0-9 within character classes like [0-9a-f] with \d improves readability.

Also, we should probably use the regexp/prefer-d rule to enforce this. I opened an issue for this: ota-meshi/eslint-plugin-regexp#341

My addition to regexp/prefer-d was just merged and will be part of the next release.

I edited this PR to only replace [0-9] with \d, [0-9.] with [\d.] and [0-9_] with [\d_], so character classes like [0-9a-z] are kept as is.
