Merge #11836: Rename rpcuser.py to rpcauth.py
3121d76 doc: Update release notes for share/rpcauth/rpcauth.py rename (Henrik Jonsson)
3fdb297 Rename rpcuser.py to rpcauth.py (Henrik Jonsson)

Pull request description:

  This script creates `rpcauth` entries for bitcoin.conf, not the deprecated `rpcuser` entry, so this changes the name of the script to match.

  As discussed in #11830.
