Update sort-ini.py script

[arilamstein]

Update sort-ini.py to work with Python 3. Also run black on script.

Note that the README specifically instructs people to run this script. So updating it to work with Python 3 seems like a good idea.

As discussed in PR #590

Could you please undo the black run on the script so that it's easier to see what really changed ?

Also: I think it's better to open the file in text mode using 'utf-8' as encoding. That way you don't need the .encode() calls.

This is a much more elegant solution than the one that I made (which was largely written by putting error messages into an LLM 😆 )

While there are no automated tests, I copied the state of config.ini from the checkin before mine (f9d4b85) and ran the version of sort-ini.py with the version of the code in this PR. The result is the same as the one in my PR that was accepted.

In short: the last 3 entries in the file are not in alphabetical order. Running the code in this PR puts them in alphabetical order (which is what I gather is the intention of the file).

LGTM

Thanks, @arilamstein

I've created PR #592 so we run sort-ini.py on the CI to ensure future changes remain sorted.
