Python retired in 2020, and some distributions do not provide the
'python' command any more.

As in commit 51839e29cb59 ("scripts: switch explicitly to Python 3"),
we need to use more specific 'python3' to invoke scripts even if they
are written in a way compatible with both Python 2 and 3.

This commit removes the variable 'PYTHON', and switches the existing
users to 'PYTHON3'.

BTW, PEP 394 (https://www.python.org/dev/peps/pep-0394/) is a helpful
material.

So this will have the effect of making the docs build impossible for
folks who only have Python 2.

Is this a problem?  Python 2 is EOL.

Everybody who wants to use Python
must install Python 3.


Rather, people are screaming
that the 'python' command does not exist.

 As I said before, this is a step that we
knew was coming, we just hadn't decided on the exact timing - I guess
this decides for us :)

That said, I'll copy linux-doc to see if anybody screams.  I assume this
is a 5.12 change?

No, I am planning to do this for 5.11
(a pull request this week if there is no objection).

Thanks,

jon
