Dependency updates and so forth

* Test against typescript@5.0

* Default to Node.js 20

* Upgrade XO

* Add reporter logs for Node.js 20

* Update dev dependencies

* Reduce timeouts in reporter tests

This may cause CI failures especially on Windows, but we do waste a lot of time with these tests.

* Inline slash dependency

We need it available in CJS but the package is now ESM only. It's more bothersome to remember to not upgrade the dependency than to inline it.

* Update dependencies

* Rebuild lockfile

* Use latest Codecov action
