Support python 3.13 (#2249)

The PR proposes to build and test with Python 3.13 in conda package
workflow.

Also default python version used by other GH actions is bumped up to
3.13 except:
- building docs because there is no support of python 3.13 in CuPy
- coverage because there is no support of python 3.13 in `coveralls`

Note, `conda-build` does not support python 3.13, but it is still
possible to install it into env with python 3.12 and to run conda build
with `--python 3.13` option.

Also it forces to pin `numpy >= 1.23` in `meta.yaml` otherwise it is
impossible to use the latest numpy version, because it is pinned to 2.0
by `--numpy 2.0` option (while numpy 2.0 does not support python 3.13
yet, it has been added later).
