@jpmmcneill Now that dbt-labs/dbt-core#5875 has been merged, just one thing and then this should be ready!

1. Restore the original version of dbt-requirements.txt

If all looks good after CI runs, then we'll merge.

@dbeatty10 it looks like tests were failing here.

I'm taking a look

Something unique about dbt-spark is that it supports several different connection methods, and we try to test all of them.
Unfortunately, we have a couple tests related to these connections that are very flakey and often fail. Since they are flakey (not real issues), we've just been ignoring these failures.

On our side, it might be worth considering if we want to just disable those CI workflows for now if we're not paying attention to them anyways.
