Attempt to build binaries with github actions (#1)

* Attempt to build binaries with github actions

* Force hot-off-the-press GHC

* Relax cabal version requirement

* Use different github actions

* Attempt to release built binary

* Put the built binary somewhere more convenient

Also fix an errant "pdf" extension

* Copy the binary after it has been built, not before

* Upload the artifact so it's there to be downloaded

* Fix typo
