Add Python 3.10 support

[ancalita]

Proposed changes:

• Update Python constraint in pyproject.toml and then lock file
• Amend CI workflows
• Fixes failing model training unit tests by decoding the temporary directory which is of type bytes in Python 3.10 tempfile module.
• Filter 3.10 deprecation warnings from failing unit tests.

Status (please check what you already did):

• added some tests for the functionality
• updated the documentation
• updated the changelog (please check changelog for instructions)
• reformat files using black (please check Readme for instructions)

lgtm 👍 great work, digging into the dependency updates.

do we also want to update the python version used in our docker containers or should that be separate?

@tmbo I believe it's separate work. Infra will take care of that: they needed to upgrade the OS of docker images to address vulnerabilities, but the upgrade was blocked because the next ubuntu version pins 3.10. So I think it's going to be done as part of that work. (this ticket). I will double check with Infra to make sure this is done. Thanks for the nudge

@ancalita one dead link in the docs tests makes the check fail, but it appears the link is momentarily dead, nothing we can do about it straight away. if you can merge the PR when you're ready, LMK and I'll merge even if the check is still red

@m-vdb Yup sure, I'm now pending two things actually:

• rasa-sdk alpha release
• feedback from @twerkmeister on that rasa interactive width calculation function

[twerkmeister]

@ancalita I am not sure what the width calculation refers to - can you give me some pointer at what to look at? I can't see any specific question about it

Sure @twerkmeister Here is the calc_true_wrapping_width() code, this is the unit test, the last test case fails with AssertionError: 59 != 60 only with Python 3.10 + thread where this first started being discussed: #11773 (comment)
