The version of clang-format we use in the CI to format all PRs is a bit outdated, leading to some confusion when the CI job produces different output from what people have locally.

We should decide on a policy for updating this version since it impacts the whole monorepo, and we should document the version currently in use somewhere (in the Contributing docs?). We should also decide on a policy for whether to re-apply clang-format to the whole codebase whenever we change this version.
