Buat fungsi parseWorkflowTriggers(yaml) yang menerima string simplified workflow YAML dan mengembalikan array trigger events.

Input format (baris per baris):

on: push, pull_request
branches: main, develop

Yang perlu di-extract: value setelah on: dipisah koma dan di-trim.

Contoh: parseWorkflowTriggers("on: push, pull_request") → ["push", "pull_request"]

Hint

• GitHub Actions workflow dijalankan berdasarkan triggers.
• Trigger umum: push, pull_request, schedule.
• on: push → trigger saat push. on: pull_request → saat PR.
