       windows binaries: bump python version (3.7.9->3.8.7)
       
       Had to also bump ubuntu version 18.04->20.04,
       as was getting errors running the self-compiled pyinstaller otherwise (weird...):
       
       ```
       from .utils.git import get_repo_revision
       ModuleNotFoundError: No module named 'PyInstaller.utils'
       ```
       (similar to https://github.com/pyinstaller/pyinstaller/issues/4403 )
       
       -----
       
       Note re appimage: when trying to compile python 3.8.x on ubuntu 16.04, I am getting:
       
       ./Modules/posixmodule.c: In function ‘os_copy_file_range_impl’:
       ./Modules/posixmodule.c:10351:15: error: implicit declaration of function ‘copy_file_range’ [-Werror=implicit-function-declaration]
                ret = copy_file_range(src, p_offset_src, dst, p_offset_dst, count, flags);
       
       This is because ubuntu 16.04 has too old glibc.
