Remove mention of GitLab 18.0 removal
What does this MR do?
This MR removes the reference to the %18.0 removal of runner registration tokens when using the register command with any of the runner manager-specific arguments.
I also increased the timeout for the code_quality job, as it was being hit.
Why was this MR needed?
We're no longer removing them in %18.0. No new milestone has been announced.
What's the best way to test this MR?
N/A
What are the relevant issue numbers?
