Fix error in tests using paramiko > 4

Description

Do not import directly paramiko.DSSKey as it does not exist in paramiko > 4
And try also to fix other non-related errors, to make the tests pass.
The only unresolved problem is the security issue with the cryptography library, but newer versions require Python 3.11 or newer. So I will keep it until we decide to move the tests to a new python version.

Pull request overview

Updates the project’s pinned dependencies and related code to keep the test suite compatible with newer Paramiko releases (>= 4 / now pinned to 5.0.0), while also refreshing a few related dependency/CI components.

Changes:

• Avoid direct use of paramiko.DSSKey (removed in Paramiko >= 4) when building the SSH private key type list.
• Bump Paramiko to 5.0.0 and update the lockfile accordingly (including newly required transitive deps like invoke).
• Minor updates to integration test client construction and CI workflow dependencies/actions.
