📝 Summary

• Extract function to parse and change the yaml files into its own file for testing purposes
• Installed uvu for testing
• Added basic test suites to assure the parse function:
  • It modifies the file when there's setup-node step without cache option
  • It bumps to setup-node to v2 if it is not already bumped
  • It does not modify the file if no step contains setup-node
  • It does not modify the file if setup-node has cache option already
