Remove package build-types directories when cleaning (#61939)

Stale generated types can be left sitting around the repo which can cause build issues. Gutenberg recommends using the `clean:package-types` command to clean types and fix this problem, but the generated declaration files remain.

This can cause issues with builds that are resolved by removing the stale declaration files (put in the build-types directories) and getting a fresh build.
