sagemath-9.5: package updates and fixes
#### Testing the changes
- I tested the changes in this PR: **YES**

This includes
 - upgrade to lrcalc-2.1 (from #36209)
 -  _already merged_ ~upgrade to sympy-1.10.1 (from #36397)~
 - _postponed_ ~upgrade to SuiteSparse-5.11.0, igraph-0.9.7, planarity-3.0.2.0, python3-cvxopt-1.3.0 (from #36423)~
 - _already merged_ ~upgrade to giac-1.7.0.53 (from #36421)~
 - _already merged_ ~upgrade to gp2c-0.0.12pl1 (from #36422)~
 - backported fixes for sagemath-9.5 to accomodate these upgrades, and also ipython and scipy upgrades which are already merged

~I want to see if the CI can cope with this. Otherwise I'll just split this in a few separate PR. Except for the upgrade to lrcalc-2.1, which must be coordinated with sage, everything else can be handled separately.~

EDIT: I ended up making 3 new PR to handle the packages that can be upgraded separately from sagemath (#36397, #36421, #36422, #36423 should be ok to merge if CI passes).

EDIT 2: this PR is now just to upgrade lrcalc to 2.1 (will be needed for sagemath-9.6) and fix sagemath-9.5 so it works with lrcalc 2.1 (and several minor doctest fixes for upgrades to ipython, scipy, sympy).
