Fails to build with Python 3.12

[mat813]

I am not sure why this fails, but:

$ docker run -it --rm python:3.12 pip install chkcrontab
Collecting chkcrontab

  × Building wheel for chkcrontab (pyproject.toml) did not run successfully.
  │ exit code: 1
  ╰─> [1 lines of output]
      error: can't copy 'doc/chkcrontab.1': doesn't exist or not a regular file
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.
  ERROR: Failed building wheel for chkcrontab
Failed to build chkcrontab
ERROR: ERROR: Failed to build installable wheels for some pyproject.toml based projects (chkcrontab)

It works just fine with Python 3.11.
