What does this MR do and why?

This MR replaces create with build_stubbed in spec/serializers/lfs_file_lock_entity_spec.rb to optimize the factory usage as recommended in our handbook. This spec is part of the list .rubocop_todo/rspec/factory_bot/avoid_create.yml. It was verified that database persistence is not needed using the factory doctor command FDOC=1 bin/rspec spec/serializers/lfs_file_lock_entity_spec.rb.
