Upgrade eslint-plugin-unicorn to version 63.0.0

This is a major version bump, but the changelog at
https://github.com/sindresorhus/eslint-plugin-unicorn/releases/tag/v63.0.0
doesn't indicate any breaking changes that should impact us.

Note that this version supports ESLint 10, which is a prerequisite for
being able to upgrade ESLint itself in a follow-up later.
