Vinyl lower bound has to be bumped due to a recent GHC 9.2 fix. union currently tests from GHC 8.2 onwards. Turns out Vinyl broke GHC 8.4 support in a recent release, and GHC 8.2 isn't supported either. So this PR drops support for those. I don't see any reasons not to support them, so I made a PR here: https://github.com/VinylRecords/Vinyl/pull/168 . If the old support matters, this PR should perhaps wait until that one is resolved.
