Bug#1027947: python3-setuptools-scm: needs depend on python3-tomli during Python 3.11 transition

[Timo Röhling]

Package: python3-setuptools-scm
Version: 7.1.0-1
Severity: serious
Justification: missing dependency causes FTBFS in unrelated packages

Dear maintainer,

python3-setuptools-scm has a 'python3-tomli || python3 (>> 3.11)'
dependency, which breaks python3.10 builds now that python3 has
transitioned to 3.11 as default version.

Adding python3-tomli unconditionally until Python 3.10 is dropped
from the archive will resolve the issue.


Example build log excerpt from ros-catkin-lint follows:

The above exception was the direct cause of the following exception:
