Rollup merge of rust-lang#139028 - Noratrieb:ping-pong, r=RalfJung

Make target maintainers more easily pingable

Put them all on the same line with just their GitHub handles to make it very easy to copy and paste (with ctrl-shift-v!!!) the names.

We have no use for email, so I removed all the emails, we don't care about people's full names either.

This is a pretty big PR with lots of changes. I may have gotten one or two wrong, who knows. I went over it fairly aggressively, removing all information I deemed unnecessary.

> [!Caution]
> When copying these usernames, use **ctrl-shift-v** to avoid pasting them as links

r? RalfJung you indirectly asked for this :) (anyone is welcome to review)
