The homebrew statement "bottle :unneeded" is deprecated and needs to be removed

[paltherr]

The statement "bottle :unneeded" in the homebrew formula zunit.rb is deprecated:

https://github.com/zunit-zsh/homebrew-zunit/blob/master/Formula/zunit.rb#L14

It prevents homebrew from installing zunit:

% brew install zunit-zsh/zunit/zunit
==> Tapping zunit-zsh/zunit
Cloning into '/usr/local/Homebrew/Library/Taps/zunit-zsh/homebrew-zunit'...

zunit: Calling bottle :unneeded is disabled! There is no replacement.
Please report this issue to the zunit-zsh/zunit tap (not Homebrew/brew or Homebrew/core):
/usr/local/Homebrew/Library/Taps/zunit-zsh/homebrew-zunit/Formula/zunit.rb:14

Error: Cannot tap zunit-zsh/zunit: invalid syntax in tap!

Removing the statement should resolve the problem.
