Improve SSH commit signing instructions

[nopeitsnothing]

Changes proposed in this PR:

• Add alternative for SSH signing in git for WSL

This PR is to suggest a WSL method for assigning a SSH git key using the xclip command, rather than pbcopy.
Saves people time figuring out Ubuntu doesn't have the pbcopy package, and is pretty straightforward.

Perhaps we should make some mention of wl-copy from Ubuntu and Fedora.

mm, instead I've just updated this PR to have the command point to a file containing your public key, rather than pasting your public key at the end of the command. This seems to be the recommended (by GitHub) way to do it now anyways, I'm not sure why the instructions didn't do this before, unless this behavior wasn't supported by the very first implementation of SSH key signing in Git? 🤷‍♂️

(i.e. git config --global user.signingkey /PATH/TO/.SSH/KEY.PUB instead of git config --global user.signingkey 'ssh-ed25519 AAAAC3(...) user@example.com')
