This resolves permission failures when modifying root-owned files
and such, e.g., modifying /etc/hosts. It had been possible
to work around this by adding alacritty to the set of
applications with "Full Disk Access" in System Preferences. macOS
now opens a prompt to confirm permission with a new installation.
This fixes#2337.
This adds the new Alacritty icon to the macOS binary available in the
github releases. On sizes 128x128 and up the image with scanlines is
included.
The ci deployment process should now also offer the svg file for
download so the .desktop file can be used without having to look through
the repos for the icon.
