libraryLink attribute in Footprint class missing

[mvnmgrx]

This MWE does throw an attribute exception:

from kiutils.kiutils.footprint import Footprint

footprint = Footprint(version='20220512', generator='mygen')

footprint.to_file("test.kicad_mod")

Traceback (most recent call last):
  File "e:\etc\projects\py-pingen\pingen.py", line 8, in <module>
    footprint.to_file("test.kicad_mod")
  File "e:\etc\projects\py-pingen\kiutils\kiutils\footprint.py", line 854, in to_file
    outfile.write(self.to_sexpr())
  File "e:\etc\projects\py-pingen\kiutils\kiutils\footprint.py", line 876, in to_sexpr
    expression =  f'{indents}(footprint "{dequote(self.libraryLink)}"{locked}{placed}{version}{generator}'
AttributeError: 'Footprint' object has no attribute 'libraryLink'

Fix:
In footprint.py -> class Footprint() the token version is defined twice. One of them should be libraryLink, as already documented there.
