inno: bump keyring to 18.0.1 to avoid AttributeError (issue6043)

The error seems to be harmless, because it happens after closing the connection.
For whatever reason, this isn't bundled with the Wix installer.

# simple script to be used in hooks
#
# put something like this in the repo .hg/hgrc:
#
#     [hooks]
#     changegroup = python "$TESTDIR/printenv.py" <hookname> [exit] [output]
#
#   - <hookname> is a mandatory argument (e.g. "changegroup")
#   - [exit] is the exit code of the hook (default: 0)
#   - [output] is the name of the output file (default: use sys.stdout)
#              the file will be opened in append mode.
