Update of git-hooks (uses Python 3.x)?

[Martin Liška]

Hello.

Note that binutils updated the git-hooks, which now uses Python 3:
https://github.com/AdaCore/git-hooks

I'm asking because we're facing again an encoding issue (spotted by Jakub):

<jakub> remote: Traceback (most recent call last):
<jakub> remote:   File "hooks/post_receive.py", line 118, in <module>
<jakub> remote:     post_receive(refs_data, args.submitter_email)

<jakub> remote:     return _iterencode(o, 0)
<jakub> remote: UnicodeDecodeError: 'utf8' codec can't decode byte 0xe9 in position 7675115: invalid continuation byte

So can we please update the hooks?

Thanks,
