Replace last mention of IRC with Discord

Mozilla's IRC service was shut down in March 2020. The official
instant messaging variant has been Discord for a while, and most of
the links were already replaced by #61524.

This was the last line that came up with `irc.mozilla.org` or any
combination of "irc.*#[a-z]+" in a `git grep`:

    git grep -i -E "irc.*#[a-z]+"

As there is only one other link directly to Rust's discord, I used the
same Markdown link `[rust-discord]` as in `bootstrap/README.md` to
stay consistent. This might come in handy if the chat platform changes
at a later point again.

As an aside: for those interested in the use of IRC, Mozilla's [wiki]
still offers a lot of in-depth knowledge.
