chore: Update Renovate config (#769)

# Summary

Updates renovate config to use the
[`config:best-practices`](https://docs.renovatebot.com/presets-config/#configbest-practices)
preset rather than the `config:base` preset since `config:base` seems to
be deprecated.

Also updates the `schedule` config to use the
[`schedule:monthly`](https://docs.renovatebot.com/presets-schedule/#schedulemonthly)
preset.

Also adds a pre-submit to run the
[`renovate-config-validator`](https://docs.renovatebot.com/config-validation/)
to ensure that renovate config is valid. This pre-submit will need to be
made required in the repository branch protection rule for `main` in the
repository settings after this PR is merged.
