My proposal is suitable for this project

• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Description

eslint/eslint#18007 was rejected as a breaking change enhancement.

Given this impacts us directly (eg #8251) we should build this into our fork.

I propose the following changes:

1. if the test case has output and the output value is a string and the test case requires more than 1 pass to fix then the test case fails with a message like "test requires multiple fixes to resolve due to overlapping fix ranges - please use the array form of output to declare all of the expected fix passes".
2. accept an array for output which declares the expected fix passes for a test case.
   • An array of size 0 is disallowed.
   • An array of size 1 is equivalent to the string form.
   • An array of size n asserts that there are exactly n fix passes
   • The rule tester asserts that after each fix pass the output matches the nth element of the array.
