Modify Renovate configuration for improved management

[jimboid]

Summary

This change should set up renovate to properly deal with dependencies in a python project managed by actions.

Changes

• removed duplicated options in config.
• actions are hived off into a group and pinned to semver.
• core dependencies are grouped and are under the widen strategy which is more conda and pip friendly
• dev tools and flit are grouped under a CI group and are pinned on latest since we don't care if these track latest and in some ways they should

Impact

The impact of this is that we will have renovate properly set up to version deps using a widen strategy which is more like what a project like this should have. Since this code is often installed next to other codes we need wider support for more sw versions, not just tracking latest. This will also fix the in-range strategy not matching any updates when a range is supplied in the project toml that tightly limits updates to ranges that enclose the range to lower than newer releases.
