Add official support for Python 3.13 (#13309)

* Add official support for Python 3.13

This commit adds "official" support for Python 3.13 to Qiskit. We
implicitly supported it previously because nothing in Qiskit itself was
incompatible with 3.13 and we use the stable ABI from rust which is
compatible with new releases. But to mark 3.13 as "official" we just
need to add it to CI, including the cibuildwheel test phase, and add the
trove classifier to the package metadata indicating 3.13 is supported.

* Remove scipy pin on 3.13

* Fix docstring tests with 3.13 indent rules

* Add 3.13 to asv config too
