Update dependencies and new release

[XSpielinbox]

1. The Dockerfile is still using Python 3.9. Is there any special reasoning behind that? If not, I would suggest updating to the python:3-slim image, that uses Python 3.11 and automatically switches to newer stable 3.x versions, when available, lowering the maintenance burden.

2. The Snap still uses core20. Would an upgrade to core22 be possible?

3. After these updates and the large amount of changes since 2.5.0, it would be nice if a new version would be released, that then can be packaged and downloaded by users.

Thanks in advance. If I can help in any way, please let me know.

A release is coming soon, actually! I was hoping to have it done by the end of this week, but some of the outstanding issues are taking me a bit longer than expected. I'd like to get the following issues closed:

• builtin hardened policy vs ED25519 CA #120 (I have 80% of a patch done for this already)
• JSON output does not have a recommendations section #122 (There are two community-written PRs waiting in the queue)
• Python file #145
• LookupError: unknown encoding: idna #152

Updating the Docker and Snap base images were already in the plan as well. Those should be very easy to do.

@jtesta - Do you think it's strictly necesarry to wait for all the items above to be resolved before publishing a new release?

Quite a few fixes and enhancements have accumulated under v2.6.0-dev now...

@thecliguy : Good news! I've completed the bulk of the work I mentioned above! All that's left is a little bit more testing, then the packaging for the new release can start. ;)

@XSpielinbox , @thecliguy : v2.9.0 has been released! Thanks for all your help!

Shouldn't it have been 2.6 ?
