Website: show whole shell command at once

[birkenfeld]

Since the TLS related options were added, the main https://rustup.rs/ page shows only a fraction of the shell command (see below).

Even copying the command is getting cumbersome with this, and it would be nice to see the whole thing I'm supposed to run...

I'd love it if someone would contribute an HTML/CSS update to fix this.

I'm no good at modern CSS, unfortunately.
