What does this MR do and why?

This MR replaces create with build_stubbed in spec/presenters/ci/group_variable_presenter_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/presenters/ci/group_variable_presenter_spec.rb.

Factory Usage Optimization Results

Before optimization:

  • Factory time: 0.978s (5.46% of total time)

After optimization:

  • Factory time: 0.007s (0.05% of total time)

🚀 Improvement:

  • Factory time reduced by: 0.971s
  • Factory time percentage reduced by: 5.41%
  • Overall factory usage improvement: 99.3%
