Replace eslint-plugin-sort-exports by eslint-plugin-perfectionist

The `eslint-plugin-sort-exports` plugin doesn't support ESLint 9 or has
published plans to do so. The `eslint-plugin-perfectionist` does support
ESLint 9 [1], seems more actively maintained [2, 3] and contains other
rules that could be interesting later on [4]. Note that both plugins
behave the same, except for two cases which are updated here.
