When using the the dateformat of django with a date before 999 (or 99 and
9 for similar matters) and the format character "y" no leading zero will
be printed. This is not consistent with the way the python datetime module
and PHP handle that character "y" in format strings:

django (version 3.1):
{{{#!python
>>> import datetime
>>> from django.utils import dateformat
>>> dateformat.format(datetime.datetime(123, 4, 5, 6, 7), "y")
'3'
}}}

python (version 3.8):
{{{#!python
>>> import datetime
>>> datetime.datetime(123, 4, 5, 6, 7).strftime("%y")
'23'
}}}

php (version 7.4):
{{{#!php
echo date("y", strtotime("0123-04-05 06:07:00"))
23
}}}

I have a pull-request ready for this.
