I think the failed lint build is unrelated as v12.x-staging shows the same failure (https://ci.nodejs.org/job/node-test-linter/35727/)

Maybe related to backporting of #33852?

#30607 updated tools/icu/README.md and removed code blocks from the file before #33852 landed and changed/tightened up the lint rules. #30607 is marked dont-land-on-v12.x so those code blocks still exist on 12.x.

Probably the simplest thing to do is fixup the code fences in 12.x prior to cherry-picking the commit from #33852. cc @codebytere

@Flarna fixed it up on staging - if you rebase this should be good to go
