[Debian-astro-maintainers] Bug#1019708: Waiting for upstream fix

[Ole Streicher]

Control: tags -1 -patch

Upstream will fix this probably soon by merging 
https://github.com/astropy/astropy/pull/13614 into their development 
branch and backporting it to the 5.1 version. Probably then they will 
issue a bugfix version, as the PR covers all fixes for the upcoming 
Python 3.11.

I will wait for this bugfix version, as Python 3.11  will also soon 
knock on the Debian's door, and we need this anyway.
