SSH file to "id_ed25519.pub"

[servel333]

Why:

It looks like the filename was changed in the "generating a new ssh key" document, and I figure this should be updated as well.

Ref: https://docs.github.com/en/free-pro-team@latest/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent

What's being changed:

- pbcopy < ~/.ssh/id_rsa.pub
- Copies the contents of the id_rsa.pub file to your clipboard
+ pbcopy < ~/.ssh/id_ed25519.pub
+ Copies the contents of the id_ed25519.pub file to your clipboard

Check off the following:

• All of the tests are passing.
• I have reviewed my changes in staging.
• For content changes, I have reviewed the localization checklist
• For content changes, I have reviewed the Content style guide for GitHub Docs.

It's worth noting that the instructions mention using both an RSA and the other one. These two docs may need further updates in order to resolve the issue of different key names on different systems, as well as addressing legacy keys that users already use.
