chore: regroup 'support dependencies' in renovate config (#885)

## Description

This changes the grouping in renovate to group anything outside of the
`src/<package>` folders into a single `support-deps` grouping (with the
exception of pepr). I reviewed the current PRs and several previous
merged PRs and these matches should catch all the other locations we
have dependencies.

Worth noting we do not need the pinDigests option added anywhere since
uds-common includes that as a helper for actions/workflows:
