[ Impact ]

giara is completely unusable as it will fail with the below error
whenever any user tries to run "giara":

Traceback (most recent call last):
  File "/usr/bin/giara", line 87, in <module>
    from giara import __main__
  File "/usr/lib/python3/dist-packages/giara/__main__.py", line 25, in <module>
    from giara.app_window import AppWindow
  File "/usr/lib/python3/dist-packages/giara/app_window.py", line 4, in <module>
    from giara.main_ui import MainUI

    from giara.left_stack import LeftStack
  File "/usr/lib/python3/dist-packages/giara/left_stack.py", line 3, in <module>
    from giara.sections_stack import SectionsStack
  File "/usr/lib/python3/dist-packages/giara/sections_stack.py", line 3, in <module>
    from giara.markdown_view import MarkdownView
  File "/usr/lib/python3/dist-packages/giara/markdown_view.py", line 20, in <module>
    class PangoRenderer(mistune.HTMLRenderer):
AttributeError: module 'mistune' has no attribute 'HTMLRenderer'

[ Test Plan ]

* Execute "giara"
* if its not fixed then it will fail as the error above
* With fixed package the "giara" window will be displayed.

[ Where problems could occur ]

This is no change in the code, only a patch introduced in Debian has
been removed which is not needed in Ununtu. So, the chances of
regressionan are very less. Also, currently its completely unusable,
there can not be a bigger regression than that.

[ Other Info ]

The Debian patch which is removed in this change was updating it to use
a later version of python3-mistune. But the version of python3-mistune
in Jammy is 2.0.0-1+really0.8.4-1 wich is actally the old mistune
0.8.4-1 and so the Debian patch is not needed in Jammy.
