Revert "Upgrade Azure SDK and Jackson (#72833) (#72995)" (#73837)

The recent upgrade of the Azure SDK has caused a few test failures that
have been difficult to debug and do not yet have a fix. In particular, a
change to the netty reactor resolving
(https://github.com/reactor/reactor-netty/issues/1655). We need to wait
for a fix for that issue, so this reverts commit
6c4c4a0ecbc140b6dbb37df77c8282ffa63e4891.

relates #73493
