reuse 6.1.1

v6.1.1

on Python PyPI

Changed

• In the Docker images, Alpine is bumped to alpine:3.22 and Debian to
  debian:13-slim. (#1247)

Fixed

• ASCII frames around comments were broken in v6.0.0. They now work again. The
  sole condition is that the 'suffix' of a comment is identical to its 'prefix'.
  For example:

  /*******************************************\
  |*  SPDX-License-Identifier: CC-BY-SA-4.0  *|
  \*******************************************/
