Merge branch '/mahf708/ipd/dependabot' into next (PR #6163)

With this, dependabot will perform dependency checks on things we use inside
GitHub Actions at a configurable frequency (for now, weekly). If there are
updates, it will issue a PR requesting reviews from members (for now, Luca and Naser)
and assigning the PR to an integrator (for now, Rob).
