build: Renovate changes

Ensures that the core configuration focuses on keeping the development
branch updated, while also proposing security fixes for backporting
branches.

The core configuration is scheduled for Tuesdays and Thursdays only. The
backporting schedule is disabled, as its execution closes open PRs by a
separate configuration (e.g. the core config).
