In 16709c6, @matthewrobertson bumped @types/express from 4.17.21 to ^5.0.0, which probably wasn't intended.

This causes issues, because the RouteParameters type in @types/express-serve-static-core, which is used by @types/express, changed slightly between v4 and v5

This caused unexpected issues for us when upgrading dependencies in https://github.com/mdn/yari/blob/main/cloud-function/package.json, as @sentry/google-cloud-serverless 8.54.0 expects express v4 types.
