.gitgo line collapse change after writeFile() execution

[rchtgpt]

Describe the bug
After the writeFile() function is executed, the .gitgo file collapses into a single line. We don't want that.

To Reproduce
Steps to reproduce the behavior:

1. Run gtg start
2. Enter an issue number
3. Select an issue type
4. Press Enter and head over to .gitgo file

Expected behavior
Everything should be in a well-formatted structure and not just in a single line.
