node: upgrade mocha from 8 to 10

[link2xt]

Even upgrading to Mocha 9 with npm install mocha@9 does not just work. Changelog says that at version 9.0 "Mocha is going ESM-first!".

npm run test fails with an error:

$ npm run test

> [email protected] test
> npm run test:lint && npm run test:mocha


> [email protected] test:lint
> npm run lint


> [email protected] lint
> prettier --check "node/lib/**/*.{ts,tsx}"

Checking formatting...
All matched files use Prettier code style!

> [email protected] test:mocha
> mocha -r esm node/test/test.js --growl --reporter=spec --bail --exit
