py-MechanicalSoup: updated to 1.2.0

Version 1.2
===========

Main changes

* Added support for Python 3.10.

* Add support for HTML form-associated elements (i.e. input elements that are
  associated with a form by a ``form`` attribute, but are not a child element
  of the form.)

Bug fixes

* When uploading a file, only the filename is now submitted to the server.
  Previously, the full file path was being submitted, which exposed more
  local information than users may have been expecting.
