Revert "Bump to ADAM 0.23.0 release. (#4044)"

[droazen]

This reverts commit 8a366c7.

We noticed a major performance regression in BaseRecalibratorSpark and HaplotypeCallerSpark after we upgraded our ADAM dependency (see #4376). This PR reverts that upgrade for now until we understand the underlying cause.

I ran the exome pipeline again with these changes and the performance regression went away.
