Correct tests and improve documentation 

The tests for the "Array findFromLast" proposal were originally authored
based on related tests that had already been merged to the repository's
`main` branch [1]. While those new tests were under review, a number of
tests for the Resizable ArrayBuffer proposal were found to be incorrect
[2]. The problem was fixed for the tests in `main`, but because the
corresponding tests for "Array findFromLast" were not yet merged, the
error persisted there [3].

Apply the same correction to the new tests.
