Dear Maintainer,

When installing python3-deprecated, if and only if pypy3 is installed, I'm getting the following errors:

    Failed to byte-compile /usr/lib/python3/dist-packages/deprecated/classic.py:   File "/usr/lib/python3/dist-packages/deprecated/classic.py", line 33
        type WarningAction = Literal["default", "error", "ignore", "always", "module", "once"]

This is similar to: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1136119

So probably fixable by using an appropriate X-Python3-Version to debian/control.
