Close temporary file after writing parsed test results

[hamir-suspect]

We are opening the same file multiple times:

tmpFile, err := os.CreateTemp(dirPath, "result-*.json")
			if err != nil {
				return err
			}

and then again in the cli.WriteToFile: (here)

			_, err = cli.WriteToFile(jsonData, tmpFile.Name())
			if err != nil {
				return err
			}

Since we are looping over paths we need to close the file explicitly and not using defer statement.

@hamir-suspect good catch, but I think we also should fix the creating the file twice.

What if we create a WriteFile function which receives an *os.File (and not explicitly closes it), so we let the caller handle opening and closing the file.

func WriteFile(data []byte, file *os.File) (string, error) {
	return writeToFile(data, file)
}

👏🏻 Looks good to me. I'll release a new version of the CLI later this week.
