Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Expected

eslint.config.js should be as straightforward as possible to automate. This is both to make #1670 easier and to remove unintuitive ad hoc preferences from its contents.

Actual

There are a few differences.

The biggest right now is the way plugin entries in the array are ordered. It's ... kind of alphabetical? They're somewhat in alphabetical order at first for direct property accesses and spreads thereof, and then objects in order of files - sort of?

Also, ignores isn't fully alphabetical, and linterOptions could be collapsed into one line.

Additional Info

Split out of #1670.
