Change the default editor name in first timers guide to Gedit

[Poonam Mishra]

Currently in the First timer's quickstart guide, the default command for copying SSH key is `less ~/.ssh/id_rsa.pub`.
https://docs.openstack.org/contributor-guide/quickstart/first-timers.html#set-up-ssh

here, `less` doesn't copy the content directly, plus changing it to `gedit` will maintain consistency in the document (as before using gedit as a text editor is mentioned).

I added the link. Kindly check

@mish24 When I read the link, gedit is one of GUI editors in Linux environment and other editors such as Atom and vim are also mentioned. Just changing from less into gedit would not guarantee consistency I think. Moreover, less is basic command in Linux/Mac environment (without installation) whereas gedit requires GUI environment.

So, I would like to leave the status still "Incomplete".

You don't need an editor, you just need to see the content. less is perfect for this - we expect a command line elsewhere.
