This PR adds parallelism similar to our existing circleci setup for
running yarn tests with the various test params. It does this by
sharding tests into `$SHARD_COUNT` number of groups, then spawning a job
for each of them and using jest's built in `--shard` option.
Effectively this means that the job will spawn an additional (where `n`
is the number of test params)
`n * $SHARD_COUNT` number of jobs to run tests in parallel
for a total of `n + (n * $SHARD_COUNT)` jobs. This does mean the
GitHub UI at the bottom of each PR gets longer and unfortunately it's
not sorted in any way as far as I can tell. But if something goes wrong
it should still be easy to find out what the problem is.
The PR also changes the `ci` argument for jest-cli to be an enum instead
so the tests use all available workers in GitHub actions. This will have
to live around for a bit until we can fully migrate off of circleci.
