Allow AGP 8.3.0 to be used with desugaring enabled (#2364)

## Goal

The code used to check `!AgpVersion.isAtLeast(AgpVersion.AGP_8_3_0)` but a refactor turned it into `agpExtension.version <= AgpVersion.AGP_8_3_0`. Restore the old logic so 8.3.0 becomes a valid version again.

## Testing
This will be tested in a test that Fran is adding
