Remove/Replace DSSKey references from Airflow

Body

As seen from: #54078, which is a short term fix to workaround DSSKey

Remove DSSKey references entirely in the codebase
Bump minimum to paramiko 4.0+
Provide migration guide for users with DSA keys
Bump types-paramiko version that was limited in Restrict typing-paramiko to < 4 as we do with paramiko #54173

Migration that could be required:

Users would need to:
Generate other keys to be used in their connections (RSA, ECDSA, or Ed25519 keys) and update their Airflow connections to use those

@joshuabvarghese Feel free to reach out to me if you need PR review or clarification on this issue 🙂

are there any updates on this 👀

open PR WIP #54165

Until this merges the workaround is to use env var _PIP_ADDITIONAL_REQUIREMENTS: ${_PIP_ADDITIONAL_REQUIREMENTS:-apache-airflow-providers-ssh paramiko>=2.9.0,<4.0.0}

I'm picking this up

@rawwar

After #64299 we no longer have sshtunnel dependency so I think we can proceed with fixing this issue cc @rawwar
