feat: renovate – use best-practices

Even if not wished: `config:base` should be replaced with `config:recommended`. The latter is part of config:best-practices (see: https://docs.renovatebot.com/presets-config/#configbest-practices).

We also might want to add: [`config:semverAllMonthly`](https://docs.renovatebot.com/presets-config/#configsemverallmonthly)
