Boolean literal argument without parameter name

Reports call arguments with Boolean type without explicit parameter names specified.

When multiple boolean literals are passed sequentially, it's easy to forget parameter ordering that could lead to mistakes. Explicit parameter names allow for easier code reading and understanding.

Example:

  fun check(checkName: Boolean, checkAddress: Boolean, checkPhone: Boolean) {}

  fun usage() {
      check(true, false, true) // What does this mean?
  }

The quick-fix adds missing parameter names:

  fun check(checkName: Boolean, checkAddress: Boolean, checkPhone: Boolean) {}

  fun usage() {
      check(checkName = true, checkAddress = false, checkPhone = true)
  }
