fix(layout): Update Ergo‑L layout to 1.0 version. (Nuclear-Squid)

[Nuclear-Squid]

Description

Hi ! This PR aims to update the Ergo‑L layout to it’s 1.0 version. The name of the layout has been changed from ergo-l to ergol since the config system doesn’t allow dashes in the name. (It’s also completely fine to spell “ergol” without the dash). The updated version of ergol only has a few symbols changed but is now up to date. I don’t think changing this layout would be a problem for users since it’s still a very simplified version of the layout (the altgr layer and custom dead key are not present here), and Ergo‑L users already have the layout installed on their machine.
