What are the ramifications / potential risks of operating a Rotax 592 on 93 octane fuel instead of 95 octane at the Highveld altitude ?

We have always run 582s on 93 without issue.

As somebody who knows very little about 2 strokes, can somebody explain what difference using 93 vs 95 would make? Would using 95 in a 582 be bad for the motor?

Lower octane fuel burns faster than higher octane fuel but generally has a slightly higher energy value. This means that you may even get slightly higher performance from 93. The compression ratio is low enough to use 93 safely.
