PyInk formatting issue for multi-line docstrings.

[veritas9872]

Hello, I have tried out the new PyInk pre-commit, and I have found a difference with the behavior in Black.
For multiline docstrings in file definitions, PyInk appears to move the last triple double quotes to the end of the last line instead of giving them their own line.
For example,

"""This is my file.
It works like this.
"""
import something

becomes as follows.

"""This is my file.
It works like this."""
import something
