Make rule in renovate to autoapprove and automerge PRs for certain packages

Few packages used in .github workflow can be auto-approved and auto-merged to remove noise and streamline our workflow

The suggested tools that can be auto-merged are

- github/codeql-action/init
- github/codeql-action/analyze
- Azure/setup-helm
- hoverkraft-tech/compose-action

Not an exhaustive list but more actions can added to the list as required

This does not have the actions updated by [copier](https://github.com/DiamondLightSource/blueapi/blob/632479d2da650832151bb2f3a965769e0e412388/renovate.json#L20-L33)
## Acceptance Criteria
- A rule is added in rennovate to update the above mentioned tools
Docs [here](https://docs.renovatebot.com/configuration-options/)
- These PR should only be merged once every 2 weeks to reduce noise in the main commit history
