To make the release process a bit smoother and prevent a freeze of the
master process while review candidates are out, this will put the master
in a perpetual development state.
This should make it clear to everyone that the official source for
releases is always the tagged branch and make it possible to release new
versions completely independently.
Since versions are bumped after each release, this makes it so the
release branches do not have to get merged back into the master branch
to show the correct development version.
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.
