[PATCH] Add Sync capability to Alacritty terminfo

[Christian Dürr]

In version 0.8.0 Alacritty added support for synchronized terminal
updates as documented here:

https://gitlab.freedesktop.org/terminal-wg/specifications/-/merge_requests/2

The proposal itself does not specify any detection for this feature,
since it was not expected that detection was necessary. However the tmux
implementation introduced the `Sync` capability to remedy this.

While I am unsure about the adoption of this capability, it is currently
part of the Alacritty terminfo and necessary to make synchronized
updates work in tmux. So I think it's appropriate to add this to the
ncurses definition despite no other terminal offering this capability.
