build(docs-infra): pin git ref for cli command docs (#26391)

The JSON files from which cli command docs for angular.io are generated
is broken on master (e.g. angular/cli-builds@e0ec86757), which cause foc
generation (and CI) to fail.

Pinning the git ref where we pull cli sources from to a version that is
known to be working (until we figure out what the best approach is)
