Fix release and do another RC: v0.32.0-beta.2

[tcharding]

The changes in this release do not need a changelog entry because they are:

• Remove doc_auto_cfg
• Re-order args in deprecated method we just added already (changelog mentions it already).

I noticed the arg thing while doing the upgrade in bitcoin and have tested the change.

Changed rc to beta in PR description. Can't edit the commit message but I'll live with it. The code is correct.

Super frustrating. My local CI is failing with

which I have a local patch which I thought fixed :/. Will prod at it a bit. The test makes sense, we shouldn't have to remove it, and yet it's been so flakey..

Fixed the commit log, no sure why I didn't do that yesterday. Sorry to make you run CI again.

[apoelstra]

No worries. My CI box was down for the last 24 hours anyway (moving my homedir from btrfs to ext4). It's nice to have an easy PR to make sure it's back up and running now.

LFG, soon as this is released I believe we can do the first bitcoin 0.33.0 RC

[apoelstra]

Queued. Should be less than an hour.
