Could you upgrade Asyncssh in netdev

[LF3551]

I have this problem

netdev with asyncssh<2.0,>=1.15
and scrapli with asyncssh<3.0.0,>=2.2.1

Could you upgrade netdev with new version Asyncssh and make compatibility

[heyglen]

AsyncSSH 1.18 is also throwing security alerts from pyup.

Reproduce on windows:

python -m venv .venv\
.venv\Scripts\activate.bat
pip install -U pip
pip install -U wheel
pip install netdev
pip install safety
safety check
