In #4954 we saw the Lint/CheckJS job fail:

Error: Process completed with exit code 1.

In dev/release/utils-prepare.sh we run npx --yes napi version which, when it writes out new package.json files, doesn't add trailing newlines. I think we should reformat after we run napi so this PR adds an npm run fix after we run napi version so the result of napi passes our lint step.
