Update renovate config (elastic#184785)

- Replace the `extends` config from the deprecated `config:base` to
`config:recommended`.
- Removes global defaults from top-level group and applies the
`prCreation` and `stabilityDays` options only to non-elastic dependency
groups.
- Replaces deprecated `stabilityDays` option with new
[`minimumReleaseAge`](https://docs.renovatebot.com/configuration-options/#minimumreleaseage).
- Replaces all `matchPackage*` options to `matchDep*` options.
- Format entire config file with prettier.
