causatune won't install on python>=3.10

[ZmeiGorynych]

Describe the bug
When I try to pip install causaltune under Python 3.10 or higher, it fails because there is no version of dowhy 9.1 for those Python versions.
We should bump the dowhy version (and if necessary the econml version) so that doesn't occur.

To Reproduce
Run pip install causaltune under python 3.10 or higher.

Expected behavior
pip install causaltune should work for all python versions supported by causaltune and econml.
