Upgrade alacritty_terminal in hopes to avoid PTY poll failing (#6715)

We saw stack traces in our #panic channel pop up that failed on this
line:


https://github.com/zed-industries/alacritty/blob/33306142195b354ef3485ca2b1d8a85dfc6605ca/alacritty_terminal/src/event_loop.rs#L323-L324

With this message:

thread 'PTY reader' panicked at 'called `Result::unwrap()` on an `Err`
value: Os { code: 9, kind: Uncategorized, message: "Bad file descriptor"
}'

/Users/administrator/.cargo/git/checkouts/alacritty-afea874b09a502a5/3330614/alacritty_terminal/src/event_loop.rs:324

We don't know how to reproduce the error. It doesn't seem related to the
number of open PTY handles, because `openpty` itself didn't fail. We can
only assume that something went wrong between `openpty` and the setup of
the polling.

Since Alacritty itself changed its polling mechanism significantly by
switching from `mio` to `polling`
(https://github.com/alacritty/alacritty/pull/6846) we upgraded with the
hope that this will fix the bug.


Release Notes:

- Upgraded alacritty_terminal to newest version in order to hopefully
fix a rare panic that can occur when starting a new terminal.
```
