add windows and mac support

[rochdev]

What does this PR do?

Add tests in CI for Windows and macOS to officialize support for them.

Motivation

Windows tests are failing in dd-trace because of a transitive dependency of sketches-js, indicating a potential issue with Windows support.

I don't think we want this here. This prettier/prettier ESLint plugin is reading the settings from the prettier.config.js file, so any formatting-config changes we'd make should go in prettier.config.js

I'm guessing that if you ran into an issue with this, instead of swapping the default value for endOfLine, we should set up a pre-commit hook to run prettier with the project's configuration (or make sure that your local editor is set up to run prettier itself).

The problem is that Windows uses CRLF, and by default Prettier enforces LF only. So the build fails on Windows because of this limitation. I can move the rule to prettier.config.js, but the rule is still needed.

@brimtown When I add a Prettier config file, it looks line the ESLint config file starts to be ignored. From the information I found online, I think when both Prettier and ESLint are combined then any Prettier configuration should be done in the ESLint configuration. Please let me know if you know of a way to use both.
