chore(ci): align renovate config with amp repository (#13)

Adopt the amp repository's renovate policy and dependency grouping, curated to the crates actually present in the ampup workspace.

- Defer cargo patch bumps to the scheduled `lockFileMaintenance` PR by disabling per-patch update PRs
- Add a `tokio-futures` group covering `tokio` and `futures`
- Trim the `console-rs` group to `console` and `dialoguer` (drop `indicatif`, absent from the workspace)
- Remove the `serde_yaml` ignore as the crate is not present in the dependency tree
