Update to node20

[Marv51]

I am getting a deprecation message about node 16:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: garygrossgarten/github-action-ssh@release. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

I am not sure what exactly deprecated means in this context. Potentially in the future, this action will stop working on normal runners?

I see that this action hasn't been updated in a while, but it works great for me. Please consider updating the action for this.

The node version has been updated in the latest release 0.8.0. Thanks for your patience.
